This time, under the guidance of Yang Meng,

Xiao Yi described the current problem in a way that he could understand.

After listening to Xiao Yi's narration,

Yang Meng looked out of the porthole,

When he was in the outer reaches of the Rutan star system, he could still faintly see the binary star system in Nanhe-3.

But at a distance of 6,700 astronomical units from Nanhesan,

The light emitted by Nanhe-3A, the main sequence star of Nanhe-3, has completely overshadowed the light emitted by the companion star Nanhe-3B.

The reason for this is also because Nanhe 3b is not a star, but a white dwarf.

Astronomical theories deduced from human observations,

This kind of celestial body, which is generally the corpse left behind after the death of a star,

Because the white dwarf itself is no longer able to carry out continuous and stable nuclear fusion,

This kind of corpse can only be regarded as a hot corpse, and it can maintain a certain temperature while it is hot

Therefore, compared to the extremely weak light emitted by the star, it is like a red-hot iron ball, which is detached from the heat source and thrown into a cold place, which can only be cooled slowly.

It's just that the efficiency of heat conduction in the universe is not high.

The heat of a white dwarf doesn't disappear quickly,

Just as the Earth has been around for 4.5 billion years since its birth, there are still molten hot cores in the Earth's interior.

That's how the state of the three bs of the South River is,

Although Nanhe 3b is the corpse of a dead star, the volume is only about twice that of the sun,

But because of the collapse of the star when it dies, the density of this white dwarf is extremely terrifying.

Therefore, it has twice the mass of Rutan and 0.6 times the mass of the Sun.

As the main-sequence star of Nanhe 3a, it has 1.5 times the mass of the Sun.

At such a mass, the gravitational perturbation caused by the two celestial bodies in Nanhe III is extremely complex.

If you think of space as a calm lake,

These two celestial bodies in Nanhe III are like two large and small stones thrown into the lake,

In the universe and the waves it stirs up, it swings around with two stones and the landing point as the center, and there will be a complex interweaving of waves.

And at this time, the spaceship crashed into such a wave area,

"I didn't expect the gravitational environment of the binary star system to be so complicated!"

Yang Meng knew that the gravitational environment of the binary star system might be very complicated, but he didn't expect it to be so complicated.

Looking at the extremely bright star outside the porthole, he thought about the next solution,

In fact, the way to deal with this gravitational disturbance is very simple.

All you need to do is slow down the speed of the ship.

If it were a spacecraft from his grandfather's time, the gravitational disturbance would have been almost negligible.

But in this era, his Boundless Orient is racing in the universe at 17% of the speed of light.

At this speed, any external force exerted on the spacecraft will be infinitely amplified.

If Nanhe-3 were the gravitational field of a single star like the solar system, the spacecraft might be able to pass near the solar system at the current speed.

After all, the gravitational field of the solar system is very peaceful.

As long as you master the angle and speed of entry, you can enter the solar system with a comfortable attitude, and will not affect the external structure of the spacecraft due to external forces.

However, the gravitational field of a binary star system is much more complex than that of a single star system.

At this point, the ship must slow down in order to enter.

And if the spaceship is to slow down, it will affect many things.

The angle and speed of the three gravitational fields of the Nanhe River need to be constantly adjusted and re-planned.

This will also affect the entire voyage of the spacecraft.

So many important parameters need to be changed, which has also become one of the reasons why Xiao Yi woke him up.

"Xiao Yi, prepare to slow down!"

When sorting out the current situation, Yang Meng did not hesitate too much,

Deceleration is the only option,

According to the original plan, the spacecraft would begin to slow down at 3,400 astronomical units at the center of gravity of the South River.

Apparently the plan can't keep up with the change,

He can only slow down from his current position.

When Yang Meng decided to slow down, Xiao Yi also immediately began to execute the deceleration command, accompanied by the slight vibration of the spacecraft.

The ship's brake thrusters begin to ignite in a pulse-like manner,

Yang Meng on the spaceship only felt a slight inertia, but soon this inertial force also disappeared.

Yang Meng no longer had any obvious feeling on his body, and the spaceship didn't seem to be slowing down at all.

But it is clear that the spaceship is slowing down, and the reason why it is in such a state is

Or to protect the structure of the spaceship, as well as the safety of the personnel and equipment inside the spacecraft, so the starting deceleration is not large.

And as time passes, the degree of deceleration will slowly increase.

At the current speed, the process of deceleration is bound to be a very long and slight process.

Seeing that the deceleration has begun,

Yang Meng began to plan the next sailing route with Xiao Yi.

According to the plan, when the spacecraft reaches a position of 3400 astronomical units away from the gravitational center of Nanhe San, it will use the gravitational force of Nanhe San to start braking and adjust its direction.

Along the periphery of the Nanhe three-star system, in a spiral curve, towards the target position of 1,800 astronomical units away from the center of gravity,

According to the data transmitted by Xiao Yi using radio astronomy telescope detection,

In that position, there is a large unknown celestial body,

After some data analysis, it can be preliminarily determined that the object may be a large planet and most likely has its own satellite system.

For the situation that there is a massive planet so far away from the star, Yang Meng was a little surprised at first,

You must know that the planet Rutan B is only 0.09 AU away from Rutan.

The farthest planet from Rutan is only 2 astronomical units.

Even the farthest planet from the Sun in the solar system is only 30 astronomical units.

But considering the complex gravitational state of Nanhe San,

It is very likely that its planetary system has a great eccentricity,

Taking into account eccentricity, it is not unusual for a large object to be so far away from the center of the star.

For example, some dwarf planets found in the outer reaches of the solar system have extremely exaggerated eccentricities.

How a dwarf planet numbered 2003 VB12, later named Sedna,

This spherical red object that can maintain hydrostatic equilibrium,

About 70 astronomical units at the closest point to the Sun,

And at its farthest from the sun, it is almost close to 1,000 astronomical units,

With such a strange eccentricity, after the discovery of this celestial body, astronomers in human beings can't help but suspect that there is a tenth planet outside the solar system, interfering with the normal operation of this dwarf planet,

With the development of astronomical observation technology,

Astronomical researchers in human beings, more inclined to another inference,

This dwarf planet is the solar system orbiting the Milky Way in a 220 million-year cycle.

The wandering planet captured by the solar system, which has the strange eccentricity of Sedna,

As for why this dwarf planet wanders,

According to some theories, there are two possible reasons,

One is that there are some anomalies in the star system where Sedna was originally located.

If a star reaches the end of its lifespan and there is a violent eruption,

pushed Sedna out of the way,

Another is that Sedna comes from a multi-star system.

In a multi-star system, the individual stars snatch and disturb the planets of other stars,

so that these planets are thrown around, forming complex orbits,

Some of them were thrown out by accident.

And in the Nanhe three-star system, these two situations happen to exist at the same time,

This galaxy has had both stellar explosions and complex planetary orbits because it is a binary star system.

So it's normal to have some planets with a lot of eccentricity.

The existence of this celestial body also became an important factor in his trip to Nanhesan.

"It's a pity that the track parameters have to be changed now!"

"Xiao Yi, according to the current situation, how long will it take to reach the target celestial body?"

"It's going to take about seven months!"

Hearing Xiao Yi's answer, Yang Meng nodded lightly,

Seven months was not too much for him to accept.

In his grandfather's time, this was the average time for Earth to rush to Mars.

The average distance at that point is about 0.5 astronomical units.

And now he can reach the target planet 4,000 astronomical units away in this little time.

"Xiao Yi, how much does the speed of the spaceship need to be reduced?"

"Slowing down to 13% of the speed of light is currently needed!"

Yang Meng asked Xiao Yi for the parameters of various data, and at the same time planned the next sailing route in the orbit control system.

After he was busy for a while,

The physical discomfort had to make him stop what he was doing.

"It seems that the bodily functions have completely recovered from hypothermia!"

Yang Meng touched his stomach,

Drifting towards the cabin on the side, when he passed by the dormant platform where Xiaoguang was,

glanced at the little light, which was barely flickering,

Seeing Xiaoguang in such a state, Yang Meng shook his head lightly and went to work on the current important matters first.

Although Yang Meng has come out of the state of cryogenic and dormant,

But some of the sequelae caused by dormancy are still affecting his body.

Compared to the brain that recovers first,

The recovery of bodily functions is slower,

At this time, the protective solution reserved in his body has been absorbed by the body.

Hunger and thirst caused by human bodily functions forced him to eat.

He found the tryboard and took out the space meal that had been stored for five years.

I checked the package, and then opened the seal on it.

A piece of white creamy toothpaste-like food was squeezed out of it, and with Yang Meng's squeezing action, the toothpaste-like food floated in the air.

I saw Yang Meng open his mouth, and inhaled the food into his mouth,

Although this food was made by him five years ago, it is still within the expiration date.

After all, his previous dormancy required a twenty-year cycle, and if the shelf life was too short, some problems might arise.

While eating food, Yang Meng communicated something with Xiao Yi:

"Xiao Yi, has the earth's periodic communication been smooth in the past five years?"

"Through the relay communication satellite of the Rutan, four communication packets have been received so far!"

"Only four copies in five years!"

"Yes!"

Hearing Xiao Yi's response, Yang Meng frowned slightly,

He glanced at the earth time displayed on the operation panel,

According to the normal periodic communication, he should receive five packets.

Thinking of this, Yang Meng opened the communication list:

"What cycle of communication packets did not arrive?"

With doubts, he saw that the communication of the first cycle after leaving Rutan did not arrive smoothly,

This unreached communication cycle is preceded by a communication packet with a complex encryption routine and an escalated awareness guard.

"What went wrong that didn't make the year's cycle communication go uneventfully?"

Yang Meng groaned,

According to his memory, in the hundreds of cycles of communication he has had with Earth,

Although there have been periodic communication delays, there has not been a loss of communication in a certain year.

After all, the terrestrial aspect with which he communicates is not an ordinary individual, but one of the most powerful human forces of humanity today,

If there is a possibility of personal forgetfulness or negligence, resulting in loss of communication,

However, the space agency of his force has always been known for its rigor, and this situation rarely occurs.

"Could it be that there is something wrong with the relay satellite?"

Yang Meng's first thought was that the relay satellite had failed.

"But if there is a problem with the relay satellite, the next few communication packets should not be received!"

"Moreover, I have more than one relay satellite in the Rutan system!"

In order to ensure smooth communication, he placed communication relay satellites at different locations in the Rutan system, in order to smoothly relay information from the earth.

"What's more, I should have just left Rutan at that time, and the chances of this happening should not be high!"

Thinking of this, he put the object of suspicion on the earth's side.

"Maybe the answer lies in the next four communications!"

At this moment, Yang Meng wanted to know the content of the communication,

But these four communication packets are still in a state of envelope, although they do not have the complex encryption methods on the packets containing the awareness protection upgrade program before.

But these four data packets are not sent explicitly, and have normal encryption methods.

It will also take a little time to unravel these encryption methods.

As for getting information from Xiao Yi, it is even more impossible

As an artificial intelligence program, Xiao Yi is not qualified to read letters from the earth, which is the permission set when Xiao Yi was implanted.

Everything has priorities,

Yang Meng understands that the most important thing at present is to complete the setting of the next route.

In this way, the spacecraft can decelerate along the set orbit parameters.

As for the periodic communication sent by the Earth, it is there, and it is not too late to read the letter from the ground after the orbital parameters are set.

At this time, the space meal in Yang Meng's hand had been eaten.

No longer uncomfortable in his abdomen, he put the bag into the recovery device on the side, floated to the control cabin in front of him, and continued his previous work.

The calculation and setting of track parameters is not an easy task.

Especially in the context of a binary system,

The gravitational perturbation points that need to be considered in orbit calculation are more complex,

Fortunately, his target point was still a certain distance from the two celestial bodies of Nanhe San.

The day after Yang Meng woke up from cryogenic hibernation, he and Xiao Yi finally modified the new orbital parameters.
