The entire Sirius binary system covers far more than the solar system. www.biquge.info The Oort cloud in the Solar System is only about 0.8 light-years away from the Sun, while the Oort cloud in Sirius is up to 1.6 light-years away from the common center of mass of this binary star system.

Even the planets of the Sirius binary system are located farther away than the Oort cloud in the solar system.

Perhaps it is precisely because these planets are so far away from Sirius' binary that scientists on Earth are unable to detect the existence of these planets at all.

Perhaps, this is the reason why human astronomers believe that there are few planets in binary star systems.

But in fact, whether it is a star system with a single main star, a binary star or a multi-star system, there are planets. It's just that in a binary or multi-star system, those planets that are too close to the main star have long been divided by the main star, and the planets that are too far away are simply impossible to observe in terms of the current observation technology of earthlings, which leads to the emergence of that erroneous statement.

However, Tang Feng did not have the consciousness to change this erroneous statement. If human beings want to develop, they must go through a series of failures, successes, failures, and successes. Just like before the emergence of Copernicus, earthlings believed that the earth was the center of the universe, and this erroneous understanding has been with earthlings for thousands of years.

Although this situation is also a mistake, on the other hand, when human beings have the technology to discover and correct such mistakes, is it not the best manifestation of human development?

With such a large binary star system, once it is completely controlled, it will allow the star core to control a lot more dark energy. Therefore, Tang Feng did not hesitate to take control of Sirius A.

Although Sirius A is much more powerful than the Sun in size, mass, and temperature, the brightest star in the sky is still docile as a little sheep in front of the core, without the slightest resistance.

But Sirius A is a superstar after all, so it is still difficult for Tang Feng to control.

It took Tang Feng 58 days to control this big guy, and as for the star core split, he directly used out a full 700 pieces!

Arguably, Sirius A is by far the longest time it has taken to control the core of a star other than Earth.

However, when Tang Feng completely controlled this huge star, the dark energy that the star core could control directly increased several times. The dark energy of this star alone is almost equivalent to the dark energy of all the star systems controlled by Tang Feng before.

After successfully taking control of Sirius A, Tang Feng once again turned his attention to Sirius B, about 0.16 light-years away from Sirius A, the largest white dwarf discovered so far.

The reason why the star core is magical is that it is magical in this place. As long as the star core can control the dark energy, then no celestial body in the universe can escape the fate of being controlled by the star core. Of course, it also depends on how much the star core controls the dark energy. Just like Tang Feng's star core now, it may be easy to control a star like the sun, but if it is allowed to control a neutron star or even a black hole, Tang Feng will turn back and leave without saying a word.

Youma, that's not control, that's looking for death.

Not to mention extreme celestial bodies such as neutron stars and black holes, even if they are white dwarfs, to be honest, Tang Feng is a little stunned.

White dwarfs are also a type of extreme celestial body. The reason why it is called extreme celestial body refers to the fact that this type of celestial body has one or more extreme characteristics. Let's not talk about neutron stars, a neutron star material the size of a hair is larger than Mount Everest......

White dwarfs are not as variable as neutron stars. state, but it's not a joke. Otherwise, Old Man Andro would not have risked his life to collect the core material of a white dwarf to build the Nautilus.

A white dwarf is a type of star with low brightness, high density, high quality, and high temperature, usually from a star with low to medium mass to a star of later age.

After a star passes through the main-sequence phase, it ends its nuclear reaction dominated by hydrogen fusion, and then begins a nuclear reaction dominated by helium fusion, which is the process of trihelium fusion in which helium is burned into carbon and oxygen, and expands into a red giant.

In the red giant stage, the periphery of the red giant will expand violently, but its inner core will shrink violently inward under the reaction force, and the compressed matter in the inner core will continue to become hotter, and eventually the temperature of the inner core will exceed 100 million degrees, so helium begins to fuse into carbon. Over millions of years, the red giant's helium core burns out, eventually forming a spherical core with carbon as the core, hydrogen as the shell, and a layer of helium in between.

At this time, the outer part of the red giant star will become extremely unstable, and when this violent pulsating oscillation reaches its limit, the red giant will explode, throwing all the material outside the core away from the star itself, and the matter will spread outward to become a nebula, after a large amount of mass loss. If the remaining nucleus is less than the Chandrasekhar limit (1.44 times the mass of the Sun), the star may evolve into a white dwarf, if the remaining material is greater than 1.44 times the Sun and less than the Oppenheimer-Volkov limit (3.2 times the mass of the Sun), then the core will evolve into a neutron star, but if it is greater than 3.2 times the mass of the Sun, then the core will continue to collapse gravitationally and eventually form a black hole.

Through the formation of white dwarfs, we can see that white dwarfs are usually composed of carbon and oxygen. But it is also possible that the temperature of the core can reach the temperature of burning carbon but not enough to burn neon, at which point a white dwarf with a core of oxygen, neon and magnesium can be formed. Occasionally, there are white dwarfs made of helium, but this is caused by the mass loss of the binary stars.

The white dwarf in front of you is not bright, in fact, the brightness of the white dwarf is relatively low, compared to a star in the main sequence stage, the white dwarf star is only one thousandth of the brightness of the star in the main sequence stage or less.

But you must not underestimate it because of its low brightness!

The white dwarf star in front of us, which is about the size of the Earth, has a density of up to 10 million tons per cubic meter, and its surface gravity is 180,000 times that of the Earth's gravity, and its mass is equivalent to the sum of 3.3 million Earth's mass!

If nothing else, judging from these data alone, this white dwarf that looks about the size of the Earth is an extremely terrifying guy. And this big guy is not only terrifying with all kinds of data, but its constituent substances are also extremely rare. Because of its strong internal gravity, everything on this white dwarf exists in the form of electron degeneracy. In other words, the white dwarf star is much harder than diamond......

It's a planet that's harder than diamonds! (To be continued.) )
