night,

On a bench in the park, Yang Xiaoman was lying in Xu Mang's arms. At this time, Xu Mang was confirming the news with Professor Smith. The so-called American Astronomical Society had long been in conflict with the Princeton Astrophysics Association, mainly because of

Academic competition is quite fierce.

"Professor Smith?"

"I heard that at the International Astronomical Conference in a week, the American Astronomical Society will publish a research report on the binary star system in Sagittarius?" Xu Mang asked curiously: "Is it true? If it is true, then this is

It’s very troublesome...I’m also studying the binary star system in Sagittarius.”

Hearing Xu Mang's words, Smith was stunned for a moment and said hurriedly: "How is your progress? If possible, compete with them. It is best to complete the research on the binary star system in Sagittarius before the start of the international astronomy conference.

The release of the report made the American Astronomical Society depressed."

"..."

"It seems that Professor Smith, our ideas have collided." Xu Mang said with a smile: "But I need financial support and a little bit of equipment support, otherwise I cannot guarantee that I will be able to do it before the international astronomy conference.

Study out success.”

"rest assured!"

"We will do our best to help you. After all, you are a core member of our Princeton Astrophysics Association." Professor Smith smiled: "Xu Mang... publish the success on the homepage of our association and I will promote it."

"good!"

"I will!" Xu Mang said, "I'll hang up first."

snap,

hang up the phone,

Xu Mang glanced at the girl in his arms, with a hint of shyness in his eyebrows. Although he didn't know why this happened, it was conceivable... At this time, Xiao Man was filled with an inexplicable impulse. If it weren't for

In a public place like this in a park, I'm afraid... I will die.

"husband..."

"Let's go home!"

"oh."

this night,

Nothing happened, but Xu Mang knew that the real challenge would be tomorrow night.

The next day,

Xu Mang returned to his workplace. There was no one in the entire research institute today. After all, everyone was on holiday. Xu Mang was not a black-hearted boss like Xiao Man. He forced his subordinates to work hard. He wished he could work sixteen hours a day and have nothing to do all year round.

stop.

Sitting in his office, Xu Mang opened his mailbox. As expected, there was an additional email in it. He clicked on it and read the information about the binary star system in Sagittarius sent by Professor Smith.

I have to say,

This information is very detailed, much more detailed than what I and Brother Chuan Xiao collected. Sometimes I have to admit that in the field of cosmology, developed countries are indeed very advanced. This must be admitted. China still has a lot of ways to go.

Gotta go.

Judging from the current development situation, the pace of catching up is quite positive. We are working hard to explore space. Fat Five has succeeded again. The Taibai Cat Mars rover is ready to go. Everything is ready and we are just waiting for some details.

Next,

Based on the information obtained, Xu Mang began to conduct more in-depth research on this star system. He couldn't help but find that this binary star system was different from others. To be precise, it was a unique existence. It was brighter than all other known eclipse-changing binary stars.

100 times greater, and powers massive stellar winds equivalent to those of the most massive stars before they die.

And these two extreme properties are because the normal star is four times more massive than the white dwarf. In all other known eclipsing binaries, the white dwarf is more massive than the orbiting normal star, which is just the opposite.

So far,

Xu Mang made a relatively complete physical model. Based on this model, he basically predicted that in the next few decades, the fate of the binary star system in Sagittarius will spiral rapidly with the increase in brightness. Inevitably, this

This spiral rotation will reach its climax, and most of the gas in the normal star will fall onto the white dwarf in the last few weeks and days.

This falling mass will release huge gravitational potential energy, driving unprecedented stellar winds, all of which will reach its peak in the last few weeks and days, and the Big Bang will reach its peak brightness within a month, two

stars merge into one star.

at last,

The result of the merger will be a single star with a degenerate white dwarf core, a hydrogen-burning layer, and a huge envelope of gas, mostly hydrogen.

I feel excited just thinking about it!

Xu Mang is 100% sure of his predictions, all of which use standard equations that describe many physical mechanisms. Although the exact time cannot be calculated yet, he has given a strong answer.

but,

It is now possible to calculate the time, based on the brightness at which the spiral merger occurred. The uncertainty in this date is plus or minus sixteen years, due to the huge inherent jitter in brightness in the historical record, which does not perfectly measure the doubling time scale.

therefore,

This time may be around 2100, or to be more precise, between 80 and 100 years, most likely near the middle of this range.

"no!"

"We have to calculate the exact time!" Xu Mang's head suddenly stiffened again. He was so stubborn that he had to calculate the exact time, otherwise he would feel very uncomfortable.

However,

He overestimated himself and spent an hour in the morning. He couldn't calculate the specific explosion time. Xu Mang couldn't help but give up. Unless more bright galaxies could be provided, it would be impossible to find them from some current data.

What can be done.

...

afternoon,

Xu Mang drove to Xiaoman's company, and sure enough... one-third of the people stayed in the company to work overtime. There was no way... triple pay was no joke, three days was equal to the normal ten days.

"Eh!"

"Look at yourself... you're a black-hearted boss!" Xu Mang sat in front of Xiao Man and said with a look of disgust: "Do you know what a statutory holiday is? It's a day that is fixed by law as a day off, and what about you?

Look what you are calling this, it is illegal!"

"Knowing the law and breaking the law...the crime will be increased by one level." Xu Mang said seriously: "The person who came...taken him out and chopped him up!"

Yang Xiaoman:(*￣︿￣)

Damn it!

This bastard is being mean again,

I am angry with you every day. When I have a child... I will give you to the eunuch!

"snort!"

"You are so arrogant now... Look at me, I can't kill you in the future." Yang Xiaoman said angrily: "By the way, where are you going to eat tonight?"

"Of course it's a French dinner!" Xu Mang said with a smile: "I just made a reservation, and by the way...I also booked a room in the hotel, and then...went to the supermarket and bought a few

Secondary gun holster."

After saying that,

He walked up to Xiao Man, grabbed her delicate hand, put it into his pocket, and said with a wicked smile: "Hey hey hey."

"Bad guy!"

"You've been bullying me all day long." Yang Xiaoman rolled her eyes, curled her lips and said, "Husband...why do I have an illusion?"

"ah?"

"What illusion?" Xu Mang asked.

"You don't love me at all!" Yang Xiaoman pouted and said: "You didn't buy me a diamond ring, and you didn't get a decent proposal, so you got married in a daze... You are always perfunctory with me, if I didn't really love you.

, I would have chopped you to death long ago."

Xu Mang shrank his head, his face full of embarrassment, but soon his waist stiffened again. Wasn't today just to make up for these two mistakes?

"Ouch..."

"We are already an old couple, and we are still struggling with this matter." Xu Mang pinched Xiaoman's face and said helplessly: "Then what... I will provide you with it later!"

"snort!"

"Big liar!" Yang Xiaoman rolled her eyes at Xu Mang: "When in the future? When the child goes to kindergarten?"

"hey-hey."

soon,

Xu Mang took Xiao Man to the city center. Although it was not a kindergarten, for Xiao Man, the arrangement was quite satisfactory. A romantic meal and a romantic Ferris wheel time together, could this big bastard have enlightened him?

?

One meal cost nearly RMB 10,000. When it was time to pay the bill, Xu Mangtian shamelessly took Xiaoman's bank card to settle the bill. This made the violent airport so angry that he wanted to bite him.
