Chapter 261: Signal Research

The so-called variable star, as its name implies, is a star that can change its brightness. There is such a star in the universe. Their luminosity is not stable, but it will suddenly change their brightness at some point.
There are two types of variable stars, one is a pulsating variable star, and the other is an explosive variable star. While in the Sky Eagle Nebula, Xiao Yu manipulated a satellite to hit the white dwarf, which triggered a nova explosion of the white dwarf, which caused the brightness of the white dwarf to increase by tens of thousands of times in a flash. This is a typical example. Eruption variable star.
In addition to the accident of this white dwarf, the process of supernova explosion of aging stars into neutron stars or black holes is also a mechanism for the formation of variable stars. A supernova explosion was observed in ancient China. The explosion created the famous Crab Nebula. The star ’s luminosity increased by more than 100,000 times during the supernova explosion. At that time, in the sky at night, There will be two moons. Its luminosity can be seen even during the day. This is the variable star burst.
A pulsating variable star is a star's own luminosity change due to its internal mechanism during its evolution stage. This red dwarf is obviously not an explosive variable star, then it may only be a pulsating variable star, but after a simple analysis, Xiao Yu discovered that this red dwarf cannot be a pulsating variable star.
It is neither an explosive variable star nor a pulsating variable star. So what causes its luminosity change?
Xiao Yu first ruled out the possibility that the interstellar dust occlusion caused the photometric change. Because the interstellar dust cannot block the infrared, if it is caused by the interstellar dust blocking, when the luminosity of its visible light band changes, the light in the infrared band should remain stable. However, Xiao Yu saw that the visible light and infrared of this red dwarf fluctuated according to some rules.
Xiao Yu showed great interest in this.
"Is it because of some mechanism that I do n’t have that has caused this unusual photometric change? If this is true, it is a big discovery, maybe I can develop a new theory from this. . "
Xiao Yu enthusiastically arranged tens of thousands of spaceships into an array telescope array, and aimed the lens at this mundane red dwarf.
When observing the unusual luminosity change of this red dwarf, Xiao Yu keenly noticed that the ghost family attached to that star seemed to have a little fluctuation. A little movement of it caused the entire star to violently move. At this moment, the stellar wind intensity of this star increased at least a hundred times.
"Senior, what's wrong with you? Is there anything?" Xiao Yu asked with some confusion and worry.
The ghost's answer was a little hesitant. After a while, it replied: "Nothing. I have a long rest period. I always have to move my body slightly. Well, during this time, how is your technological progress OK? Did anything happen? "
"Senior, thanks to your generous shelter, my science and technology have progressed very quickly. During this time, my negative material cannon is close to the actual combat level. Breakthrough shield technology has appeared, and new computers have also been manufactured. Success. After decades, I will definitely have the ability to defeat the Morian Civilization Fleet and carry out your desire. "
The ghost race was silent again. A few minutes later, it replied: "Very good, you are doing a good job. Well, I noticed that a red dwarf star twenty kilometers away seemed to have some abnormal changes, Do you know what these changes mean? "
"Have you noticed it?" Xiao Yu said, "I am doing research in this area, and if there is any breakthrough, I will tell you."
"Well, I have an ominous foreboding. This change seems to be caused by the arrival of some malicious force. For your safety and for my last wish to be carried through, after you have the research results, you must tell I must never make a decision without authorization, so as not to cause irreparable losses. "
"Okay, I will follow your instructions." Xiao Yu responded respectfully.
At this moment, more than twenty light years away from Xiao Yu, this collective of consciousness had already left the red dwarf and was waiting for something quietly.
"According to calculations, at this time, the light from this star has passed to the main civilization, life or death is a success."
"Yes, the strange change of this star, if even the main civilization can detect it, then there is no reason that the previous generation of ghosts could not detect it. I am worried that the previous generation of ghosts will speculate that this is caused by us Will expose our arrival. "
"It doesn't matter. It takes twenty years for the transmission of light. In these twenty years, we have run a distance of dozens of light years and come to another direction. Even the previous generation of ghosts can take this To figure out what, it just knows that we are here, and because of our special hiding means, it is impossible to find out where we are. "
"The only thing that needs to be worried is whether it will be wary of the main civilization and cause the main civilization to fail to implement its own plan. But this means of communication is the only way we can think of. We can only do it here. . The rest is up to our good fortune, to see if the main civilization has enough ability to solve the current crisis ... "
"Yeah. This time, it ’s more dangerous than the last time we happened to encounter the Guardian Civilization's fleet. It was dangerous to escape the other time. Our main civilization experienced too few things, and it ’s still too easy to believe others. He I haven't comprehended this truth. In this dark universe, except us, any existence is unbelievable. Any existence will only take its own existence as the highest interest. In this universe, where will there be sacrifices? Is there a civilization that fulfills others? "
"It does n’t make sense to discuss this. Who is n’t in this universe? Even ourselves, we can't get our own development by killing the rest of the civilization? Although we are not connected with the main civilization, we cannot be with the main civilization during these times Contact, but it is foreseeable that the main civilization is in this period, and it is estimated that the extinct civilization is not a minority. "
"All we have to do is wait slowly. If everything goes well, the main civilization will definitely find a way to contact us, so pay close attention to the movement of that weird star. Our vitality is maintained by the main civilization .Everything is alive, and all is dead. "
After some debate, the ghost family hidden in the corner of the universe once again quieted down. They quietly concealed their whereabouts, relying on the phantom-specific methods to avoid the hunt of the previous generation of phantoms, waiting for the dawn of dawn in the night.
At this moment, Xiao Yu next to the strange star is still continuously observing this red dwarf. But what made Xiao Yu wonder is that the strange change in the luminosity of the red dwarf this time seems to be accidental surname, that is to say, it only appears once, and it will be gone later. At least, during the period when Xiao Yu started his observation, the red dwarf was calm and completely showed the surname of the ordinary red dwarf, without any special features.
So far, Xiao Yu has not realized that there will be some kind of signal in these changes in light, but just research it as a special phenomenon that he has not yet understood and mastered.
Looking at the calm red dwarf, Xiao Yu thought for a moment, "After solving the fleet of the Merian civilization, I must go to the red dwarf to see what it is all about. "
Thinking about it this way, Xiao Yu completely abandoned his research in this area, and instead handed all the experimental data to the Red Dwarf Research Group of the Stellar Institute of Science of the Central Academy of Sciences and let them start their research slowly. Xiao Yu On his own, he once again turned his attention to the development of science and technology ~ EbookFREE.me ~ Time passed slowly. After about a month, Xiao Yu received a message from the aging ghost family.
"My junior, how is your research on the abnormal luminosity change of that red dwarf? Are there any new findings?"
At the moment of receiving the message, Xiao Yu had a little doubt in his heart, "I always contact the seniors of the ghost family initiatively. It rarely comes to contact me actively. I have never contacted me once in a while, but For this red dwarf, it actively contacted me twice in a row. Is this red dwarf so important? "
With this in mind, Xiao Yu still respectfully responded: "Senior, I did some research on this, but unfortunately, I didn't make any progress and didn't find anything."
"Well ..." The aging ghost group groaned and said, "My unpredictable premonition is getting stronger. I have an instinct that the unusual performance of this red dwarf will be the beginning of a disaster. And you, very It may not be able to withstand this disaster and die. So, you need to step up your research in this regard, and then tell me the results of the research, and I will find a way to deal with it. "
When hearing the aging ghost clan saying so, Xiao Yu's heart was inexplicably tense. During this time, Xiao Yu had established trust in this aging ghost group, and, in the subconscious, began to regard it as his elder.
"Okay, senior, please rest assured that I will continue to carry out research in this area. If there are any findings, I will definitely tell you the first time."
"That's fine. Go on with your research. I'm going to take a break ..."
