The news that Betelgeuse has a companion star within its hydrogen envelope is truly mind-blowing.

So much so that the researchers of the Qinghai Astronomical Observatory focused almost all their attention on this news, and then ignored the data calculation methods used in the data in their hands, as well as the precise diameter and mass of Betelgeuse and other information.

After the shock, many people began to notice the calculation methods in the literature and the precise data of Betelgeuse and companion stars.

Although I can't understand the calculation formula and calculation process in the data, I can understand the final answer.

The diameter of Betelgeuse:【889.00712721D⊙】

The diameter of the companion star:【67.456799134D⊙】

The mass of Betelgeuse:【23.871911123M⊙】

The mass of the companion star: 【2.706358293M⊙】

The precise data about Betelgeuse reflected in the pupils of these astronomy researchers, causing the pupils to constrict suddenly.

Although I can't understand the calculation process, and I can't know whether the answers are correct, but these values ​​are all accurate to eight or nine decimal places without exception.

How was such accurate data calculated?

Are these answers accurate?

If it is accurate, does it mean that there is a new method of calculating star parameters in the astronomical world?

What about the formula behind it? What is the principle?

Many doubts arise in the minds of these astronomical researchers.

Thinking of a brand-new calculation method that can accurately calculate the parameters of celestial bodies in the distant starry sky to eight or nine decimal places of the traditional calculation method, everyone's breathing involuntarily became heavy and rapid.

A brand-new method of accurately calculating celestial bodies is of great importance to the astronomical community.

It is no exaggeration to say that in the mathematics world, the person who pioneered this method has a status comparable to that of Pope Alexander Grothendieck in the mathematics world.

The Pope established a new foundation on the original geometry, introduced the concept of outlines, established a set of grand and complete "theories of outlines", and completely rewrote the subject of algebraic geometry.

The impact on the mathematics community is unparalleled in modern history.

Today, if the data on the manuscript paper is confirmed, it is calculated using a brand new method, and the answer is accurate.

Then the influence of the founder of this method on the astronomical world is probably not weaker than that of the Pope on the mathematical world.

Being able to accurately calculate various information such as the mass, diameter, and volume of a celestial body means that astronomers can have a more in-depth grasp of the information about this planet.

Take Betelgeuse as an example, if you can accurately judge this information, you can judge more accurately on this basis that it has reached the stage of life, whether the hydrogen and helium in the core have been completely fused, and the distance from the supernova How long does it take to explode?

This is still a star, and it will be more effective when placed on a planet.

Apart from other things, it is of great value to be able to judge whether this planet is livable for humans.

And this series of key information can be analyzed from the data, provided that the data is accurate.

Thinking of this, many astronomy researchers in the room gathered around, wanting to ask for advice.

It's just that they found the wrong person at the first time, and found Liu Xuan from Nantah University.

Liu Xuan smiled and said, "This mathematical method was not developed by us, but by our junior students from Nantah University."

"In fact, this observation and scientific research project on Betelgeuse is not mine, and I just came here to work."

As he spoke, he pulled Xu Chuan over and introduced, "This is Xu Chuan, the proud son of the Department of Mathematics at Nantah University, a super genius, and a bright new star in the mathematics world."

"Now that I am only a freshman, I have already proved a world-class mathematical conjecture, and I hope to win the Fields Medal in two years' time."

"This project is related to the mathematical conjecture Weyl-Berry conjecture he proved before."

"Of course, it is now called the Xu-Weyl-Berry theorem. Using this theorem, it is possible to perform precise calculations on celestial bodies in distant galaxies."

"And there may be a companion star in the hydrogen envelope of Betelgeuse, which was actually discovered by him. He initially calculated two completely different diameters through data, and only then did these subsequent discoveries."

Hearing this, the researchers of the Qinghai Astronomical Observatory turned their attention to Xu Chuan one after another. After confirming that the extremely young boy in front of him was the man in the legend, they all widened their eyes and opened their mouths in disbelief.

This is the boss?

For Xu Chuan, the researchers at the Astronomical Observatory have basically heard of it. After all, there was such a big commotion a while ago. After the "Annual of Mathematics" published the proof process of the Weyl-Berry conjecture, even the news reported his deeds. All of you here have heard of it even if you haven’t seen it.

It's just that no one expected that this genius would actually come to their astronomical observatory, a poor place like no shit.

But it's no wonder they didn't recognize them. Since coming to the Qinghai Astronomical Observatory, except for meeting a deputy station chief on the first day, Xu Chuan has been living in a simple way, and he hasn't had much contact with the astronomical station. The researchers dealt with each other.

Although he has the idea of ​​communicating with astronomical researchers, the precise calculation of celestial body information by the Xu-Weyl-Berry theorem and whether Betelgeuse really has a companion star have not been fully verified.

It's okay to wait until the confirmation is confirmed to communicate, so I didn't deal with these researchers. As a result, the researchers at Qinghai Astronomical Observatory basically didn't know him.

At first everyone thought that he was a student of Nantah University who was brought by a few doctoral students to see the world, so they didn't care.

In the end, no one thought that this person was actually the rightful master.

The top scorer in the college entrance examination, IMO+IPHO double gold medal, solved a world-class mathematical conjecture when he was 18 years old, this resume, given to anyone, can make people dazzling, let alone all piled up on one person .

"Oh my god, the legendary God of Sichuan has actually come to our astronomical station."

"It's true that you don't know Taishan with your eyes. The boss didn't recognize it right in front of my eyes."

"Boss, can I ask how these data are calculated?"

"Boss, big brother, can you sign it for me! I want to go back and give it to my son, and bless him not to fail in mathematics."

"."

In the computing center, a group of astronomical researchers from the astronomical station surrounded Xu Chuan, making all kinds of flattery as if they didn't want money.

Of course, the most common thing is to ask how the data of Betelgeuse and its companion star are calculated.

On the one hand, it is love.

Those who can enter the unpopular industry of astronomy and study it in depth are basically passionate about this industry.

Just like mathematics, if you don't love mathematics, you can't learn it at all;

The same is true for astronomy. Nowadays, this industry is actually quite unpopular, and the salary and benefits are actually mediocre even if you enter a major university or research station.

And I often have to go to the barren mountains to observe various data. I was bitten to death by mosquitoes in summer, and I was frozen to death in the cold wind outside in winter. I really can't keep going.

On the other hand, scientific researchers are also human beings with families and lives. Mastering a new skill can bring them higher wages and bonuses. If they have the opportunity to master it, they will naturally not let it go.

Xu Chuan didn't mind explaining the method of Xu-Weyl-Berry theorem to accurately calculate celestial body information.

But these things are indeed too esoteric for these researchers at the astronomical station.

Even for mathematicians in the mathematics world, it is very difficult to accept these things, and they will never learn them in a short time.

So even if he talked, he just talked about some superficial things,

There is no way, a little deeper, these researchers look confused.

As for astronomers using the Xu-Weyl-Berry theorem to accurately calculate the information of celestial bodies in the universe, that will be a matter of the future.

In the computing center, everyone dispersed after chatting for a while. After all, it was already past two o'clock in the morning.

Some are doing observation and research, while others are going to sleep. As for Xu Chuan and several doctoral students from Nantah University, they are sorting out the observation data of this scientific research experiment and preparing for the subsequent publication of papers and news releases.

This time they can be said to have made a big deal, so why not be shocked at how the astronomical community can afford the busyness of these days.

Moreover, there are some differences between the publication of results in astronomy and the publication of results in mathematics.

The achievements of the mathematics world, ranging from world-class mathematical conjectures, the seven millennium problems, to the dissertations of graduate students and doctoral students, generally everyone likes to throw them publicly on the preprint server first.

For example, preprint websites such as arXiv, BioRxiv, ChemRxiv, and The Winnower.

The purpose of this is on the one hand to prevent plagiarism.

A good research result is sent out on the preprint server first, which can prevent some academically dishonest editors, reviewers, and others from stealing your research results during the long submission process.

On the other hand, it allows others to see your paper and expand the influence of the paper.

It can also allow the article to be cited by other scholars earlier, as many Nature and Science articles will do.

This point has become the default consensus in academia.

At least in the mathematics, physics, and materials circles that Xu Chuan is familiar with, this is the case.

After all, you need to know that the average review cycle and publication cycle of traditional journal papers is more than 30 days, and some even take several years.

If the author chooses not to publish the results of the paper during this period, the research progress in this field will appear "outdated", and the way of public communication of preprints will make academic exchanges smoother, and some hot fields can develop rapidly.

In addition, some manuscripts that are purely for expressing their own academic views are generally unlikely to be accepted by official journals, but the preprint server will accept them, providing a publishing platform.

Therefore, the mathematics community generally makes the results public first, and then goes through the review process.

Xu Chuan's previous weak Weyl-Berry conjecture was proved in this way. It was first thrown on arXiv, and then submitted to "New Advances in Mathematics".

As for the comprehensive process of the Weyl-Berry conjecture, there is no such thing, because it was publicly proved at the Princeton mathematics conference, so there is no need to worry about this issue.

The situation in the astronomy community is more complicated, but roughly divided into two categories according to the type of telescope.

One is a general-purpose telescope, and the other is a special-purpose telescope.

The users of general-purpose telescopes are all astronomers all over the world. Applications for use are usually collected before the observing season. The scientific committee evaluates the applications, selects good research topics, and allocates observation time.

Astronomers who get the observation time can start to observe according to the allocated time; after the observation, they will get the original data through disk or network.

But this data can only be obtained by the applicant himself. He can use this data to publish papers after conducting research and analysis, while others are restricted from applying.

However, this restriction application is valid. Once the time is up, the observer must open this part of the data to the outside world.

Different telescopes may have slightly different validity periods, some are 1 year, some are 1.5 years, some are 2 years, this is not necessarily the case.

The special telescope is optional.

You can choose to make it public and let the whole world study it together, or you can not make it public for your own research.

No way, a large number of achievements in astronomy are actually observational and data collection in nature.

For example, in this observation of the companion star inside the hydrogen envelope of Betelgeuse, a large amount of data about Betelgeuse was collected, and then Xu Chuan used these data to calculate that there is a companion star in the hydrogen envelope of Betelgeuse.

If these observational data and anomalous data are released, it is a default that you have made the data public, and other scholars can also use it.

The residual value dug out of these data and the results made do not belong to the observer of the data, but to the digger.

At most, others thank you when they publish their results.

But if you don't publish it, you can use these abnormal data to slowly discover other things in it.

Therefore, some achievements in the astronomy community will basically not be published on the preprint server until they are fully completed.

Either publish the paper directly after the research is completed, or hold a press conference directly when there are major achievements, or directly hide it and study it slowly.

As for Xu Chuan, the results will probably be made public directly.

Not only the observed companion star of Betelgeuse, but also papers on the method of using the Xu-Weyl-Berry theorem to accurately calculate the information of celestial bodies in the universe.

These things will be made public directly.

On the one hand, there is nothing to hide.

It can only be said that it is basically impossible to transform these observational data and theoretical data into scientific research results.

Is it possible that you can use the Xu-Weyl-Berry theorem to accurately calculate that a certain terrestrial planet is suitable for human survival, and then you can directly immigrate to it?

Don't dream, the farthest probe launched by human beings is Voyager 1. It has been launched into the sky for 40 years, and it has not even flown out of the solar system.

If the Otter cloud is used as the boundary of the solar system, it will take another 300,000 years to fly out of the solar system.

It is too early to think about immigration or something.

On the other hand, it is also reciprocating.

Regarding the observation of Betelgeuse, from the approval of the scientific research project, to the application for the use of the equipment of the astronomical observatory in southern Yunnan and Qinghai, and the rapid queue jumping, he was given the green light almost the whole process.

You must know that just the application and queuing for large telescopes will not be completed in a few months and half a year.

Although there are factors for winning the Fields Medal in order to enhance his influence, it is undeniable that this has saved him a lot of time and energy.
