The TRAPPIST-1 system is similar to the world, the ocean world

One of the seven rocky planets around the TRAPPIST-1 star is likely to be the world's oceanic world, scientists say, creating climatic models for the exoplanet. Researchers from the Washington University in the USA, thanks to a very hot, bright early star stage, can be developed like Venus, seven stars in the world. Any early ocean can evaporate the planet, leaving a dense, non-viable atmosphere.

Andrew Linkevski, a doctoral student at the University of Washington, said: "Not only do we think that we can balance the solar system with another star, but also model a strange atmosphere. The leading author of the astrophysical magazine said: "We did this to show how different the atmosphere might be."

39 light years away from TRAPPIST-1, the mass of the Sun approximately 9% and its radius of about 12%. The most widespread species of the universe – the relatively cool "Star of M" – has a large radius from the planet Jupiter, but the mass of masses is much greater. All seven of the seven TRAPPIST-1 planes refer to the size of the Earth and three of them are believed to be planets labeled e, f, and g in its habitat, allowing liquid water on the rocky planet to live on it.

The TRAPPIST-1 d crosses the inner edge of the dwelling area, and outside TRAPPIST-1 hour, the outer edge of the area. "The whole sequence of planets that helps us to understand the evolution of these planets, especially from our different stars, around a star that emits different light," says Linkinquski.

The radiation and chemical modalities of the group make spectral or wavelengths for each possible atmospheric gas, which makes observers better predict the search for such gases in an exotic atmosphere. Researchers use gases of gases one day to determine whether the gases have been controlled by the astronomers and the spectrum, and comparing them to describing something like the planet's composition, the environment, and possibly its evolutionary history. is written. According to him, people think about the life of the planet, as well as the stars in sunlight.

"But MnS stars are very different, so you really think about the chemical effect of the atmosphere, and how does this chemistry affect the climate," said Linkinquski. TRAPPIST-1 b, close to the star, is the dustiness of the world, and even for the sulfuric acid clouds, like Venera.

Planets c and d may be less energy than Venus and Earth at their star, and may have a cenessen, dense, adverse atmosphere. TRAPPIST-1 e – puts liquid water on a normal surface for seven people and is a good choice for further study.
The outer planetary f, g and h may be like Venus or may freeze it in the face of the evolution of water on the planet. Linkovski actually said that any SPAPPIST-1 planetary can be like Venus, that any water or ocean has been burned for a long time. When the water evaporates from the surface of the planet, ultraviolet radiation releases water molecules, releasing hydrogen, which is the lightest element and can be avoided by the gravity of the planet.

This may leave many atmospheres and leave many oxygen that can irrevocably remove the planet's water. Such a planet can have a large amount of oxygen, but it is not the case in life and it is different from what has yet to be observed.
