The other planets of this star system, apparently uninhabitable.
A new study shows that on the surface of the exoplanets TRAPPIST-1e is the water of the ocean.
The other planets of this starry system, seemingly unfit for life, have brought back the online edition of Chronicle.info with a reference for a new era.
Star TRAPPIST-1 – red dwarf small and very weak at 39 light-years from us. The mass of the star is only 8% of solar energy. Since then, astronomers have announced the discovery of seven exoplanets around TRAPPIST-1, researchers have built models and tried to determine if one of these planets was potentially habitable.
A group of scientists from George Washington University believes that the star was extremely intense in its infancy, which probably burned the planet, the surface, the atmosphere and the humidity. However, using the new modeling, the research team concluded that the planet TRAPPIST-1e may have escaped the fate of other planets in the system and could still withstand the ocean on the surface.
"We have just assumed that these planets will behave in the same way as the worlds of the solar system and have calculated the behavior of their atmospheres from scratch. It turned out that the planet TRAPPIST-1e may look like the Earth if it contains a lot of water, "said Andrew Linkowski of the University of Washington.
TRAPPIST-1b, the planet closest to the star is too hot, even for clouds of sulfuric acid, such as those observed on Venus. The planets c and d draw a little more energy from their star than Venus and they probably look like – a warm world with a thick and uninhabitable atmosphere. However, probably, this atmosphere is mainly composed of oxygen.
The outer planets of f, g and h may be similar to Venus or frozen, depending on the amount of water formed on the planet during its evolution.
