"Proxima Centauri is classified as a red dwarf star in the Sun category. However, if you want to understand red dwarfs, you have to start with Harrowtu. Chen Mengchuan hugged his daughter with a smile.

The little girl's knowledge level is already in the existence of hanging everything in the kindergarten, and she can speak well, and she spends most of her time playing with Ah Chen every day.

"Baba, what is Herotu? Is it a painting? Chen Zhihui blinked his eyes, puzzled.

"Haha, baby, a Herault plot is a scatter plot of the absolute magnitude or luminosity of the Sun relative to the type of spectrum, or effective temperature. To put it simply, the Herault chart is a graph of each sun, which can measure its temperature, color, and luminosity, and it has nothing to do with the position of each sun. Associated color - magnitude maps plot the apparent magnitude and color of stars, which are usually plotted for clusters of stars where the Sun is all at the same distance. Chen Mengchuan patiently said to his daughter.

The little girl obviously had no vocabulary to comprehend these words, frowning and pouting.

"Haha, you'll know when you're a little older. Baby. Chen Mengchuan picked her up.

"Baba, you still say red dwarf, aren't you red?" The little girl asked again.

"Okay, then Daddy will tell you. Red dwarfs, in fact, many times, are the planets that we see at night, because they are too far away from us, and the sun is very close to us, so red dwarfs look small and the sun looks big. Red dwarfs are the most abundant of the Suns, and most of them are less than one-third the size of the Sun in diameter, weight, and mass. That is, most red dwarfs are smaller than the Sun. ”

"And the surface temperature of these red dwarfs is lower than that of our sun, and the light emitted is much weaker than that of the sun, and sometimes many red dwarfs are only 1/10,000th of the brightness of the sun's light. It looks like a darkened firefly. Remember when I showed you a video of the fireflies? ”

"Yes."

"Well, it's because the hydrogen fusion inside these red dwarfs is slow, but there's also a good thing about their slow fusion, which is that they will also have a longer lifespan."

"Many red dwarfs with masses below 0.35 solar masses will have sufficient convection, and the helium will be evenly distributed inside the star without accumulating in the core, so that the red dwarf will not expand into a red giant, but will gradually shrink until the hydrogen is exhausted."

"Baba, how long will they glow?"

"Dad doesn't know how long it glows, but if it is based on scientific reasoning, they will maintain a stable luminosity and spectrum for hundreds of billions of years, but due to the limited age of our universe now, there are no red dwarfs that have developed to a later stage. So we have not observed the extinguishing of red dwarfs either. Chen Mengchuan said with a smile.

He enjoyed the feeling of holding his daughter and telling her science stories. The little guy is very curious, interested in everything, I don't know when I already know a lot about astronomical knowledge, most of them are told to her by Ah Chen, and sometimes Chen Mengchuan, or Zhao Wanyu tells her astronomical stories.

"Brother Chuan, we're going over." Zhao Wanyu walked in with a smile.

"Mom!" Chen Zhihui struggled and jumped down and pounced on Zhao Wanyu.

Zhao Wanyu smiled and half-squatted down, hugged her, and the mother and daughter kissed each other.

"Baby, Mom and Dad are going to work, can you play with Ah Chen?" Zhao Wanyu asked with a smile.

"Don't. I'm going to play with my mom. "The little girl is categorical.

"Mom asked Ah Chen to show cartoons to the baby."

"Good! Long live Mom, long live Ah Chen. ”

A few minutes later.

"Always show her cartoons, aren't you worried about her myopia in the future?" Chen Mengchuan complained.

"The intelligent soft light system of the graphene gravitational screen prevents myopia." Zhao Wanyu said with a smile.

Chen Mengchuan waved his hand helplessly, Zhao Wanyu is naturally much more familiar with the various technological applications and technological products of Tianzhi Technology than herself, and she will not joke with her daughter, it should be true.

It's also true, I look at the screen every day, and I only work a lot more time than I used to be on Earth, but it seems that eye drops don't use much, and when I used to be on Earth, I could drop a bottle of eye drops a week.

"Have you made an appointment?" Chen Mengchuan asked her.

Zhao Wanyu's smile retracted, and she nodded calmly, with a lot of determination in her eyes.

"Let's go, then." Chen Mengchuan didn't say anything more.

The two of them got on the gravitational ball together and soon flew towards the door of another dimension.

Today is a big day for Chen Mengchuan and others.

After a period of covert pushing, the entire United Nations finally understood what Tianzhi wanted to do.

Push the Earth Federation!

The nations of the earth are united!

This time, Tianzhi Technology will come to the stage!

Because Tianzhi Technology already has enough strength and enough popular support.

What Tianzhi Technology needs to do now is to gather all the resources of the entire earth and make a unified plan.

Further liberate more human population, release more educational power, and concentrate the strength of the entire human race to face the future.

For Chen Mengchuan, this is the most important thing during this time, and it is also an urgent thing.

After this time, Tianzhi Technology will strive for the greatest overall planning authority of the earth, and no one, any country, or any force can and can no longer stop Tianzhi Technology's overall planning this time.

The gravitational ball slowly landed on the square of the Dimensional Gate System.

Zhao Wanyu held Chen Mengchuan's hand and walked out of the gravitational ball.

In the whole square, there are already quite a few people walking around and watching. It was a world-class gathering. Countless representatives of the world's pinnacle regimes gathered in the Martian city - Qiming City, and everyone will truly understand Tianzhi Technology, understand the culture of Tianzhi Technology, and understand the ultimate ambition of Tianzhi Technology, which is an integration of the entire human civilization level, endless racial hatred, endless national hatred, and endless national hatred.

All the nations of the entire earth will be integrated today, will enter a new human era today, and will realize the highest social form that all nations are pursuing.

Tianzhi Technology now has the right to speak, and Chen Mengchuan does not intend to continue to be silent and quiet.

In the not-too-distant future, among the interstellar civilizations that are about to be realized, the earth must be monolithic!
