The next day, when the bright sunlight came in through the window, Xu Chuan, who was lying on the table, slowly opened his eyes.

"Hmm, did you sleep like this last night?"

Stretching his waist, Xu Chuan looked at the bright sky outside the window and muttered to himself.

Thanks to the air conditioning in the dormitory, otherwise I slept like this all night, and I would have been in the hospital this morning.

The early spring night in March was still a bit cold.

Getting up and washing up, Xu Chuan returned to the desk with a piece of bread and a cup of yogurt, and while eating, he looked at the manuscript paper on the table that was a little messy and even a little wrinkled due to sleep.

Last night, sorting out the data and deformation transformation xu-weyl-berry theorem was tossed until more than three o'clock in the night, so that in the end, he couldn't bear the red bull and fell asleep on the table.

But hard work pays off.

One night, although not enough time to transform the Xu-Weyl-Berry theorem from isospectral fluctuations to Sobolev space fluctuations, the core idea has already been partially written.

The rest is to slowly improve, and with his efficiency, it is estimated that it can be done in about two or three days.

Of course, this does not mean that it will be completely perfected to the point where it can be published in a journal, but that Betelgeuse can be calculated using the Xu-Weyl-Berry theorem after deformation and torsion.

This is not the same thing as sending a paper, which is more troublesome than this, and there are many things that need to be improved.

But there should be no time to continue to improve today.

Thinking about it, Xu Chuan stuffed the bread corner in his hand into his mouth, and after sorting out the manuscript paper on the table, he picked up his mobile phone and called his senior brother Fan Pengyue.

He had to complete the project in two days.

Although his follow-up research project on the xu-weyl-berry theorem is a green light, the formal procedure still needs to be followed, but the review time will be compressed to the extreme.

If you declare according to the normal and ordinary topics, it will definitely be too late.

There is a time limit for the application of ordinary projects, and the deadline for submission of the application is generally about one to two months.

There are many uncontrollable factors in the time when the notification time for project approval will be issued. It takes about 3 to 6 months.

Therefore, under normal circumstances, the time from the application to the approval of the project is about 3 months.

As for him, it can't be compared with ordinary topics, and the follow-up research topics on the Xu-Weyl-Berry theorem have been reported before, and the above is also a green light for rapid approval.

So in the past two days, he went to cooperate with Fan Pengyue to set up relevant projects, and then the Southern Assembly quickly transferred the project funds of 2.4 million yuan to a special account.

When the funds arrive, the research on Betelgeuse can be officially started.

.......

After tossing and turning with the senior brother for two or three days, the follow-up research project on the xu-weyl-berry theorem finally passed the review.

The special funds for the project will be credited to the dedicated account in three days, and in a few days, the various astronomical equipment used for the observation of Betelgeuse will also be vacant.

Everything went smoothly, and even the elder brother Fan Pengyue helped find a few doctoral students from the Department of Astronomy and joined the R&D team.

The hired kind, of course.

However, for these doctoral students, they are also willing to hire them, not to mention the project allowance, even if it is a reverse payment, they have to participate.

The Department of Astronomy is in NTU, no, it is a well-known unpopular major in the country, with few people, few scientific research projects, and even fewer scientific research funds.

In the past many years, students who dare to apply for astronomy majors are generally regarded as more "idealistic" because it is not easy to find a job after graduating from this major.

The main employment direction of the Department of Astronomy is to engage in scientific research institutions in applied interdisciplinary enterprises majoring in astronomy, such as astronomical observatories, meteorological bureaus, aerospace, national defense, geodesy, etc., as well as teaching and research work in some universities.

After all, in China, those who have the ability to study astronomy belong to the country's major universities, and the capitalists will not throw money into it at all, which is obviously a matter of throwing money into it without any income.

There are people who kill heads, but there are no people who lose money.

It is also a unit like the state that can invest some money to do these things every year.

Therefore, astronomical jobs belong to the kind where there are many people and there are few porridges, and they need to be fought for.

If you can participate in a large-scale scientific research project at the student level, it will definitely be of great help to your resume after graduation.

.......

In Xiaoxianzhuang, the day before the official launch of the Betelgeuse 4 Observation Project, Xu Chuan booked a private room and invited several doctoral students and seniors to have a meal together before the project was launched.

"Seniors, I wish you a glass and wish us a happy cooperation in subsequent scientific research projects."

In the box, Xu Chuan got up with a glass of beer and said with a smile to several seniors of the astronomy department in the box.

Whether it is in China or in China, such a thing as sophistication is unavoidable, but the domestic exchange of human feelings is more in-depth.

A simple meal can be exchanged for the full help of these doctoral students in the next 20 days, even if he pays for the hospitality himself, not to mention that it can be reimbursed through scientific research funds.

"Respect the god of the river."

"I wish Kawasami success in his research project."

"Come on."

“......”

Xu Chuan stood up to toast, and several doctors and brothers from the Department of Astronomy also quickly stood up, holding disposable plastic cups and suffocating the beer in the cups.

"You're welcome, everyone, you should eat and drink tonight, and I should trouble you from tomorrow."

Xu Chuan sat down with a smile, he was not very good at interpersonal relationships, but he could still handle a meal or something.

"Harm, what's the trouble with this, our astronomy department can participate in scientific research projects, which no one else can ask for."

"That's it, I've been a Ph.D. student, and this is the first time I've participated in a scientific research project."

"Kawagami, is your project this time to observe and collect information about Betelgeuse?"

At the dinner table, probably because he was not facing his supervisor, the atmosphere was much more relaxed, and after a few glasses of beer, several doctoral students and brothers gradually let go.

Hearing the inquiry, Xu Chuan nodded and said, "Well, this project is actually a derivative study of the Weyl-Berry conjecture. ”

"Betelgeuse is quite suitable, so it became a research target."

"Betelgeuse, the one on Orion's cantilever, is indeed a good subject to study, but are you worried about its supernova explosion?"

In the box, a doctoral student asked with a smile.

Xu Chuan shook his head and said, "That's not true, it's mainly to use the xu-weyl-berry theorem to make an accurate judgment on the size, diameter, and quality of Betelgeuse." ”

"Huh? Haven't the size and mass of Betelgeuse been measured a long time ago? ”

"If I'm not mistaken, it's a red supergiant with an M1-2 spectrum, located in the constellation Orion, with a radius of about 887 to 955 times that of the Sun, about 640 to 724 light-years from Earth, and an apparent magnitude of 0.0 to 1.3....."

A senior brother named Liu Xuan, a doctoral student sitting next to Xu Chuan, asked suspiciously, and then listed a series of various parameter information of Betelgeuse.

Xu Chuan smiled and said, "But it's not accurate, isn't it?" These are all valuations. ”

"For example, the quality of Betelgeuse has always been controversial, some data show that its mass is only 14~15 solar mass, but some data believe that its mass reaches 18~19 solar mass, and even 20 solar masses."

"That's right, because it's too far away, and the estimation of its quality is not accurate, so the deviation is very large."

Liu Xuan nodded, then reacted, looked at Xu Chuan in surprise, and asked, "Chuanshen, do you want to measure its precise quality?" ”

Xu Chuan nodded.

It was confirmed that the senior brother, a doctoral student in the Department of Astronomy, looked at Xu Chuan with the eyes of a monster, and the situation of the other people in the room was similar.

"Can this be done?"

After a pause for a long time, Liu Xuan asked hesitantly.

He originally wanted to say that this is impossible, after all, what the entire astrophysical community has not done, you can solve it?

But considering that the junior in front of him proved the world-class conjecture in his freshman year, and it was possible to win the Fields Medal in two years, the words that suddenly came to his lips were finally replaced by another question.

Xu Chuan grinned and said, "Of course, the xu-weyl-berry theorem is to study this, which can determine the shape and volume of the source of the information wave through the eigenvalues and boundary points, supplemented by the standing wave solution, and the separation variable method.....

"In the beginning, it was used to study two-dimensional waves, but I extended it to the high-latitude world......

Beside him, several doctoral brothers from the Department of Astronomy listened with a confused expression, completely unaware of what this junior was talking about.

Xu Chuan sighed and asked, "Okay, it seems that you didn't understand, so let me ask you a question, if there is a drum in the distance of your sight, where you can't see, and the sound of the drum reaches your ears, do you think you can judge the size and shape of the drum in the distance by the sound of the drum you hear in your ears?" ”

"Impossible!"

"How can this be judged?"

"Chuan Shen, you're afraid that you're going to have a tailwind, and you can hear it and hell."

As soon as this question came out, several doctoral students and brothers shook their heads and replied, only Liu Xuan beside him asked curiously.

"Is it possible to use the theorem you proved earlier?"

Xu Chuan shook his head: "No, it's not my research to do this, in fact, as early as the last century, mathematicians can confirm the size and shape of the drum by judging the sound of the drum, but some conditions are required." ”

"Listening to the sound to distinguish the drum shape is a two-dimensional Weyl-Berry conjecture proof, and I have extended the two-dimensional proof to high latitudes, so I can use it to judge the mass volume of stars."

"You can see a star in the distant sky as a drum, and the star's radiation waves, gravitational waves, space distortions, and other information are the key points I use to judge its precise size, volume, and shape."

"It sounds amazing, but theoretically, it's possible, and that's what I'm researching."

In the box, several doctoral students looked at Xu Chuan in a daze, still a little incredulous.

In their concept, the mass of a star is generally calculated by methods commonly used in the literary world, such as the law of universal gravitation, gravitational redshift, and luminosity reckoning.

Although the mass of stars in distant galaxies is not very accurate, there is no other way.

But now the first-year student in front of him told them that he had a better way to accurately measure and calculate the mass of stars.

Is this outrageous, outrageous opening the door, outrageous home?
