Chapter 97: There is 1 white dwarf

最近 The closest star to Xiao Yu is a red dwarf. Its mass is only about 50% of that of the sun. In the universe, this is the most common and most abundant star.
The smaller a plutonium star, the slower its fusion reaction and the longer its lifetime. The life span of the universe is about 13.7 billion years, and the life span of red dwarfs is much greater than this number. Therefore, there are currently no dead red dwarfs in the universe.
Plutonium contains several open clusters in the Skyhawk Nebula, and each open cluster has dozens or hundreds of stars. Among the many stars, this red dwarf can only be regarded as a very ordinary humble one.
Pluto stars are made up of cosmic dust, so the Sky Eagle Nebula is, of course, a huge star factory. In the Sky Eagle Nebula, Xiao Yu observed at least dozens of protostars.
The EBARA star is the embryonic stage of the star. Due to the unstable gravity, the interstellar dust cloud will collapse toward the center. In the process, it will emit infrared rays and the core temperature will increase until the deuterium fusion starts. The core will then stop contracting.
At this time, the interstellar dust cloud still falls on the original star like a raindrop, its mass will continue to increase, its core temperature is getting higher and higher, and its density is getting higher and higher, and then the fusion of hydrogen begins Now, it starts to emit considerable light and heat, which means that a star is really formed.
After the formation of a plutonium star, it will emit a powerful stream of high-energy charged particles, dissipating the interstellar dust matter that continues to surround it, and this will prevent its mass from increasing further.
In such a process, a star was created.
The huge stellar factory of the Tianying Nebula has another loud name, that is, the pillar of creation!
Pluto stars are the most important type of stars in the universe. It generously radiates its own energy, and its existence has created a good foundation for the emergence of life. Therefore, it is no exaggeration to name such a huge stellar factory the pillar of creation.
Xiao Xiaoyu saw that a mere 1.6 light years away from him, there was a stellar embryo in the stage of protostars. At its poles, powerful jets were launched, stretching over tens of billions of kilometers. Under its gravitational pull, the dust in interstellar space gathers around it to form a dust disk, which quickly rotates around it and continually converges on it. In the process, there are strong ultraviolet rays and X-rays Gamma rays burst out.
The Sky Eagle Nebula is such a magical place.
In addition to the stars, Xiao Yu also noticed several unique positions. In one of these locations, it was a little four or four light years away from Xiao Yu's target star. In this place, a star with a mass of 0.7 times the sun was moving in chaos. It spins wildly around an invisible point, and at the same time, it is losing quality at an amazing speed.
Approximately 500 million tons of material per second are involved in fusion in the sun. Among them, 4 million tons of material are converted into energy, which means that the sun loses 4 million tons of mass per second. But this star with a mass of 0.7 solar mass has a loss rate of a staggering 20 million tons per second!
According to the theory of stellar evolution, this is basically impossible. Therefore, combined with its weird orbit, Xiao Yu has concluded that it has a companion star, and this companion star is constantly following it. Snatch material from the body.
After Xu reached this conclusion, Xiao Yu began to worry a little.
If a companion star is not visible in the visible light band, it proves that its nuclear fusion reaction has stopped and its volume is small, but it has a great mass.
Xiao Xiaoyu concluded that there was a white dwarf.
白 This white dwarf, like a ferocious piranha, is quickly biting off a piece of meat from its companion.
根据 Based on the bite efficiency, it is very likely that this white dwarf will have a nova burst in the near future.
Of course, this recent period is on a cosmic scale. Millions of years later, and one second later, it is recent. However, according to observations, Xiao Yu is 95% sure that this white dwarf will have a nova burst within one thousand years.
Nova bursts are different from supernova bursts. Nova bursts can occur repeatedly on a white dwarf. Ia-type supernovae in supernovae bursts, although they also occur on white dwarfs, but the specific mechanism is not the same. Probably, among the various dead starbursts, novabursts are the least powerful.
However, even if the star with the least power broke out, it would have to collide with Muyue, and even Tianyuan A hit Tianyuan Four. It would be countless times more powerful. Xiao Yu's target star is only 1.4 light-years away from this irregular bomb, and it is likely to be affected in such a big event as a nova.
Xiao Xiaoyu considered it for a long time, but decided to continue to set the goal. There are two reasons for this. First, at such a distance, a nova burst does not necessarily affect him. Second, Xiao Yu hopes to get a chance to observe the nova burst at a close distance, which will greatly enrich Xiao. Yu's Stellar Evolution Theory.
Hiding in the pale red universe, Xiao Yu's fleet was moving fast.
On Xiao Yu's spacecraft shield, small flashes continued to erupt. Xiao Yu knew that it was caused by the interstellar dust cloud hitting the shield. Shrouded in countless tiny flashes, Xiao Yu's fleet seemed to be wearing a starry garment, gorgeous and unusual.
的 The material density here is thousands of times higher than in other places. The thick gas clouds cause Xiao Yu's fleet to be continuously slowed down. At the same time, the impact of gas cloud particles may also cause the departure of Xiao Yu's fleet. Only when Xiao Yu continuously adjusted the course and accelerated continuously, could he barely maintain the speed above 3000 kilometers per second.
Fortunately, Xiao Yu's fuel is still sufficient, otherwise, if it is used at this speed, the fuel will be used up.
As time passed, Xiao Yu was getting closer to the target star. Until now, Xiao Yu had only ten years of voyage, about 950 billion kilometers in distance.
This distance is still beyond the top of the star's heliosphere, but Xiao Yu has begun to encounter a small number of meteorite blocks. These meteorite blocks traveled through the universe along chaotic orbits.
At the stellar scale, the entire Skyhawk Nebula is a chaotic multibody system, and the operation of the planet inside the multibody system is chaotic and unpredictable, which also leads to the instability of interstellar matter. The operation of these meteorites is also Xiao Yu Unpredictable, so this often happens. In the last second, a meteorite was still flying. It seemed to disdain Xiao Yu ’s fleet, but the next moment, they did n’t know which one. Under the influence of the stars, they suddenly changed their trajectory, and rammed toward Xiao Yu aggressively, bursting into a big spark above the shield of Xiao Yu's spacecraft.
Xiao Yu was helpless about such a thing.
I met meteorite at such a long distance, which made Xiao Yu's estimate of the degree of chaos inside the galaxy a new level. It is very likely that the stellar system here is ten times and a hundred times more confusing than the Tianyuan four galaxy.
"It will take another ten years before I can reach my destination. My sailing speed is really too slow, and I don't know when I can step into the realm of fourth-level civilization and master the speed of super light." Xiao Yu somewhat Depressed thinking, "According to Luca II, the speed of the third-level civilization can reach 50% of the speed of light. When it enters the third-level civilization of the third-level civilization for hundreds of thousands of years, its speed It can also reach 5 percent of the speed of light. Hey, after reaching the target galaxy, relevant research should be carried out as soon as possible. "
萧 Under the constant brainwashing of Xiao Yu, tens of thousands of Lucas on the New Homeland have long since put their heart into Xiao Yu's Majesty. Even if Xiao Yu let them die, they would not hesitate to obey.
Within these two decades, thousands of Luca children were born. As soon as these Luca children had the ability to receive knowledge, Xiao Yu immediately organized a special school to cultivate their sense of loyalty from childhood ~ www. EbookFREE.me ~ even, the phrase "forever loyal to the owner" is written in the textbook.
Today is the time of routine reporting once a month. Xiao Yu connected with Luca II and listened to Luca II to report to her some new homes.
After quietly listening to the report of Luka II, Xiao Yu passed some information about the target star to it, and commanded: "Let your scientists plan a most feasible technology upgrade plan for me, and I will do it. reference."
Luca II respectfully agreed: "Observe your orders, master."
Xiao Yu didn't take this matter seriously. Compared with the rest of the complicated things, the Lucas were not worth the energy of Xiao Yu's betting. However, three days later, an urgent communication request from Luca II changed Xiao Yu's view.
"Master, master, can you ... can you give me more information ... yes, it's about this star field." Luca II said in a sharp voice.
Xiao Xiaoyu was a bit strange, but gave the details of the Sky Eagle Nebula to Luca II. Three hours later, Luca II sent another urgent communication request.
Xiao Yu turned on impatiently, and heard a bitter voice of Luca II: "Master, we are in trouble."
"Huh?" Xiao Yu expressed his doubts with a syllable.
"The Sky Eagle Nebula is called the Crimson Star Field within the Alliance, and the Crimson Star Field belongs to the second-level moderately dangerous area. 300,000 years ago, there was a fourth-level civilization fleet passing through this field After that, all the creatures of this civilization have undergone a terrible mutation ...
