If it loses its grip due to the gravity of the mother star, the four giant planets of the HR 8799 system will be displaced, potentially exploding in space.
By “taking a peek” into another star system, HR 8799 located in the constellation Pegasus, a team led by physicist Dmitri Veras from the University of Warwick (UK) created a computer model showing that this system will “how to die”.
According to Live Science, the apocalypse of this system will also be the date of the death of parent star HR 8799. This is a young star system, so its evolutionary stages are clearly indicated, helping to calculate how it is. “dead”. than other older star systems. The mother star HR 8799 is only 30 to 40 million years old (Our Sun is 4.6 billion years old). The planets revolve around it in a rhythmic rhythm: for example, if the farthest planet makes a revolution around its mother star, then at the same time the second farthest planet will make 2 revolutions, the next 4 and the next 4. the same 8 turns.
The article, published in the scientific journal Monthly Notices of the Royal Astronomical Society, indicates that with such a perfect orbital fusion, this star system would be very vulnerable to unexpected changes – such as when the star parent star dies and suddenly lapses. force of gravity that binds these planets to dance disappears.
The mother star will then become a red giant, while the planets will be severely displaced. “The planets will disperse their gravity from each other. The innermost planet will be thrown out of the system. There is also a chance that the victim will be the 3rd planet, or more than one planet will be thrown, or the planet will be thrown out. second and fourth planets can change position … “, explained Dr. Veras.
It would be a massive space catastrophe, with four giants as victims: each planet in this system weighs about five times the mass of Jupiter, while Jupiter is already as massive as 318 Earths.
