Chapter 932: Red Dwarf

A red dwarf is a classification of celestial bodies in the universe, which belongs to the M-type main sequence star and is a kind of low-mass star.

Lang Xiaonian believed that the huge red-brown celestial body he saw in front of him was a red dwarf.

However, this is very unreasonable.

"How could there be a red dwarf here? A red dwarf is a type of star. To become a star, even a low-mass star requires a huge mass." Someone in the team asked questions.

This doubt is reasonable.

In the universe, the types of celestial bodies are all determined by their mass.

If the mass is not up to the standard of becoming a star, it can only be a planet.

Jupiter in the solar system is the most suitable example.

In fact, some characteristics of Jupiter are very similar to a star, and its material composition is mainly hydrogen, and it also emits radiation.

However, Jupiter is not a star, nor will it evolve like one, because it doesn't have enough mass.

To be a star, there is a minimum quality standard.

This mass standard is 75 times the mass of Jupiter.

Yes, although Jupiter has some characteristics similar to stars, but to become a star, its mass must be increased by 75 times.

And, that's just the bare minimum.

This minimum standard mass is actually only 0.08 solar mass.

Red dwarfs are the class of stars with the smallest mass and the highest surface temperature.

Therefore, when Lang Xiaonian thought that the sphere he saw in front of him was a red dwarf, most people thought this idea was unreasonable.

"It shouldn't be. On this planet, there is not so much mass to form a star, even the red dwarf with the smallest mass."

Lang Xiaonian quickly swipe on the tablet, pull out the HR diagram, then point to the red dwarf logo on the top corner of the HR diagram, and said: "It really looks like a red dwarf, really, I think it's a miniature red dwarf star .”

Another member of the military scientific research class who is also familiar with astronomy pointed to the above data: "Then you also look at the mass. At least 75 times the mass of Jupiter, it is possible to become the smallest red dwarf. The mass of a star-beast planet , even less than one-tenth of Jupiter, even if the mass of the entire planet is absorbed, it is impossible to form a red dwarf."

Lang Xiaonian shook his head again, and explained with some excitement: "Gravity, the key is gravity. Let's recall, why do you need enough mass to form a star?

"And why can't low-mass stars evolve into neutron stars, or even black holes?

"The cause is not the mass itself, but the gravitational pull that the mass creates.

"The greater the mass, the greater the gravitational force, and if the gravitational force exceeds a critical value, the reminder will collapse.

"So, what really determines the properties of a celestial body is not the mass itself, but the gravitational force produced by the mass.

"Think about it, everyone, if there is an ability to increase the gravitational force, is it possible to make the celestial body evolve into a red dwarf with a smaller mass."

After listening to his explanation, everyone suddenly realized that what he said was right.

in the universe.

Only when the mass reaches 0.08 solar mass can stars be formed, and celestial bodies that do not reach this mass can only be planets or smaller stars.

However, in essence, mass is not a factor that directly affects the evolution of celestial bodies, but an indirect factor.

The immediate factor is gravity.

Those in the team who wanted to understand this began to breathe heavily, feeling that a crisis was approaching.

Because, in Ralph Cook's information on the Dominant Council, the Dominant Council has indeed mastered the four basic forces, including gravitation.

However, at the beginning, this piece of information was subconsciously ignored by everyone.

Because among the awakened human beings, the ability of "gravitational wave" has also appeared.

There was a white eagle super soldier who once possessed this "gravitational wave" ability, but later lost to Fang Yuan's fist and died in the Nanba Fissure Cave.

Humans also have a certain degree of research on gravitational waves.

So, an inherent impression of gravitational waves has been formed.

Gravitational waves are the weakest of the four fundamental forces, and their wavelengths are so long that they can hardly form destructive forces.

Therefore, when most people read the materials of the Juggernaut Council, they focused on the "strong nuclear force" and "weak nuclear force", and subconsciously ignored the universal gravitation.

However, seeing the red-brown star appearing in front of my eyes now, I felt a bad feeling in my heart.

At this moment, there was another loud noise from the tiny red dwarf.

boom!

The inner layer of the star is explored again, the mass is getting bigger and bigger, and the gravitational force formed is getting stronger and stronger, and it is still constantly devouring the surrounding matter.

Immediately afterwards, the sound of steel being broken came from beside him.

An underground tank in the team was attracted by gravity, rolled over and was sucked by the red dwarf.

The people on the chariot suddenly exclaimed.

The figure in the fiery red armor suddenly flew out, preventing the chariot from being sucked by the red dwarf.

Fang Yuan hurried up to help, dragged the people out of the car and sent them back to the ground.

Then, the God of War Red Dragon let go of the chariot.

The chariot rolled and fell into the red dwarf, slowly merging on the surface of the red dwarf at a temperature of 2,000 degrees, and finally merged with the red dwarf.

As the red dwarf star continued to devour the surrounding matter, the cave completely collapsed, and the entire reddish-brown star appeared on the ground.

Human countries saw this strange star at the same time, which immediately aroused the attention of all human scientists.

In every way, the star looks like a red dwarf, but the only thing that's wrong is its size.

The Eastern Navy Academy of Sciences immediately held an emergency scientific meeting.

Soon, geologist Zhou Wensheng submitted a document.

According to the data, since sixty years ago, the gravitational center of the star-beast planet is not at the center of the planet.

This situation is possible in planets, as long as the gravitational center shift is not particularly exaggerated, it is a normal phenomenon.

However, the shift of the gravitational center of the star animal planet is not small in terms of data.

The Academy of Military Sciences immediately sent an order to ask the frontline troops to measure the mass and density of the star beast civilization red dwarf.

However, it is very difficult to do this.

Because when human beings measure the mass of a star, they calculate it based on the gravitational force produced by the star on the surrounding stars.

That is to say, to calculate the volume of a star, it is necessary to ensure that the gravitational strength is constant.

However, the gravitational force emitted by the red dwarf stars produced by the star beast civilization will change.

Therefore, it is impossible to measure the gravitational force of the red dwarf star of the star beast civilization through the gravitational force.

In the end, based on Zhou Wensheng's data, it can be roughly calculated that the mass of the red dwarf star of the star beast civilization exceeds the mass of the volume, and the density is very high, more than 20 times that of iron.

One item of data is calculated.

When human scientists saw these data, the expressions on their faces were full of doubts and surprises.

Because the red dwarf star made by the star beast civilization is too strange.

"No, this miniature red dwarf did not appear just now. This red dwarf has always existed, and it has existed since sixty years ago. It has been hidden in the main nest of the star beast civilization. This is the reason why the center of gravity of the planet has shifted. .” In the end, the scientists of the Academy of Military Sciences gave a preliminary analysis result.
