The news that there is a companion star in Betelgeuse's hydrogen envelope is indeed shocking.

So much so that the scientific researchers at the Qinghai Astronomical Observatory focused almost entirely on this news, and thus ignored the data calculation methods used in the data in their hands, as well as Betelgeuse's precise diameter, mass and other information.

After the shock passed, many people began to pay attention to the calculation methods in the literature and the precise data of Betelgeuse and its companion star.

Although I can't understand the calculation formulas and calculation processes in the information, I can understand the final answer.

Betelgeuse’s diameter:【889.00d⊙】

Diameter of companion star:【67.d⊙】

Betelgeuse’s mass: [23.m⊙]

Mass of companion star:【2.m⊙】

.........

Accurate data about Betelgeuse came into the eyes of these astronomical researchers one after another, making people's eyes suddenly shrink.

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

How is such accurate data calculated?

Are these answers accurate?

If it is accurate, does it mean that the astronomical community has a brand new method of calculating stellar parameters?

What’s the formula behind it? What’s the principle?

Many doubts arise in the minds of these astronomical researchers.

When they thought that there was a brand new calculation method that could accurately calculate the parameters of celestial bodies in the distant starry sky to the eight or nine decimal places of the traditional calculation method, everyone's breathing became a little heavy and rapid involuntarily.

A brand new method of accurately calculating celestial bodies is so important to the astronomical community.

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

Pope established a new foundation on the original geometry, introduced the concept of outlines, established a grand and complete "general theory", and completely rewritten the discipline of algebraic geometry.

His influence on the world of mathematics is unparalleled in modern history.

But today, if the data on the manuscript paper are confirmed, they were calculated using a brand-new method, and the answers are accurate.

Then the influence of the founder of this method on the astronomical world is probably no less than the influence of the Pope on the mathematical world.

Being able to accurately calculate the mass, diameter, volume and other information of a celestial body means that astronomers can have a deeper grasp of the planet's information.

Take Betelgeuse as an example. If this information can be accurately judged, we can more accurately judge on this basis the stage of its life it has reached, whether the hydrogen and helium in the core have been completely fused, and how close it is to a supernova.

How long will it take for the outbreak to happen? Wait, wait...

This is still a star, and its effect is even greater when placed on a planet.

Apart from anything else, the value of being able to judge whether this planet is habitable for humans is huge.

This series of key information can be analyzed from the data, provided the data is accurate.

.........

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

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

Liu Xuan smiled and said: "This mathematical method was not developed by us, but by our junior fellow students at Nanjing University."

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

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

"Now that I am only a freshman, I have already proven world-class mathematical conjectures. I hope to win the Fields Medal in two years."

"This project is related to the Weyl-berry conjecture, a mathematical conjecture he proved before."

"Of course, it is now called the xu-weyl-berry theorem. Using this theorem, we can perform accurate calculations on celestial bodies in distant galaxies."

"And there may be a companion star in Betelgeuse's hydrogen envelope. In fact, it was discovered by him. He initially calculated two completely different diameters through data, which led to these subsequent discoveries."

Hearing this, the researchers at the Qinghai Astronomical Observatory all turned their attention to Xu Chuan. After confirming that the extremely young boy in front of them was the legendary person, they all opened their eyes and opened their mouths in disbelief.

Is this the elder?

Most of the researchers at the Astronomical Observatory have heard of Xu Chuan. After all, there was such a big fuss some time ago. After the "Annals of Mathematics" published the proof of the Weyl-berry conjecture, it was even reported by Renren Daily and CCTV News.

Everyone here has heard of his deeds even if they have never seen him.

But no one expected that this genius would actually come to a poor place like their astronomical observatory.

But it’s no wonder they didn’t recognize him. Since arriving at the Qinghai Astronomical Observatory, apart from meeting the deputy director on the first day, Xu Chuan has been reclusive and has not had much interaction with the people at the astronomical observatory.

Researchers have dealt with it.

Although he has the idea of ​​communicating with astronomical researchers, the Xu-Weyl-Berry theorem accurately calculates celestial information and whether Betelgeuse really has a companion star has not yet been fully confirmed.

There was no problem in communicating with him after it was confirmed, so he didn’t interact with these researchers. As a result, the researchers at Qinghai Astronomical Observatory basically didn’t know him.

At first, everyone thought he was a student from Nanjing University who was brought here to see the world by some fellow doctoral students, so they didn't pay much attention.

In the end, no one expected that this person was actually the real owner.

The top scorer in the college entrance examination, double gold medals in imo and ipho, and solved a world-class mathematical conjecture when I was only 18 years old. This kind of resume would be extremely dazzling for anyone, let alone all piled up in one person.

"Oh my god, the legendary God of Sichuan actually came to our humble astronomy station."

"It's so blind that I can't see Taishan. The boss didn't even recognize him right in front of me."

"Boss, can you please tell me how these data are calculated?"

"Boss, can you sign your name for me? I want to go back and give it to my son, so that he doesn't fail math."

"..."

In the computing center, a group of astronomical researchers from the astronomical station surrounded Xu Chuan, trying to flatter him as if they were free of money.

Of course, the most common question is how the data for Betelgeuse and its companions were calculated.

On the one hand, it is love.

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

Just like mathematics, if you don't love mathematics, you won't be able to learn it at all;

The same goes for astronomy. This industry is actually quite unpopular nowadays, and the salary and benefits are actually average even if you go to major universities or research stations.

Moreover, I often have to go to the barren mountains and ridges to observe various data. I am bitten to death by mosquitoes in the summer. I freeze to death in the cold wind outside in the winter. I can’t eat well and sleep well. The hardship is second only to geological exploration, and there is no love at all.

There is really no guarantee that it will work.

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

.........

Xu Chuan didn't mind explaining the method of accurately calculating celestial information using the xu-weyl-berry theorem.

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

Even for mathematicians in the field of mathematics, it is very difficult to accept these things, and they cannot learn them in a short time.

So even when he talked, he just talked about some superficial things.

There is no other way. If we dig a little deeper, these researchers will look confused.

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

.........

In the computing center, everyone chatted for a while and then dispersed. After all, it was already past two in the morning.

Some are doing observational research, while others are going to sleep. As for Xu Chuan and several doctoral fellows from NTU, they are sorting out the observation data of this scientific research experiment and preparing for subsequent paper releases and press releases.

It can be said that they have done something big this time. Why don't they shock the astronomical community by how they can afford to be so busy these days.

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

Achievements in the field of mathematics, ranging from world-class mathematical conjectures, seven millennium problems, to thesis papers of graduate students and doctoral students, generally everyone likes to publicly throw them on the preprint server.

For example, preprint websites such as arxiv, biorxiv, chemrxiv, and the winnower.

The purpose of this is to prevent plagiarism.

A good research result is first published on a preprint server, 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 expands its influence.

It also allows the article to be cited by other scholars early, as many Nature and SCE articles do.

This has become the default consensus in the academic world.

At least this is what Xu Chuan is familiar with in the three major worlds of mathematics, physics, and materials.

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

If during this period, the author chooses not to publish the results of the paper, the research progress in this field will appear "out of date". However, the open communication method of preprints makes academic communication smoother, and certain hot fields can develop rapidly.

In addition, some manuscripts are purely for expressing one's own academic opinions. Such manuscripts are generally unlikely to be accepted by official journals, but preprint servers will accept them and provide a publishing platform.
