A potentially habitable exoplanet discovered in a system of red dwarfs

The super-Earth LP 890-9, discovered by astronomers, has been named the second candidate among the most promising exoplanets in terms of the probability of life. The planet is 114 light years from Earth.

The new object is located in the habitable zone of a quiet red dwarf. That is to say that this planet revolves around its star under acceptable temperature conditions.

There is a significant possibility of water in liquid form, and therefore of life. The researchers published their findings in the journal Astronomy & Astrophysics.

The object was discovered by the method of transits, that is to say by the fluctuations of light in the radiation of the natal star at the times of the passage of LP 890-9 between its luminary and us.

An international team of scientists has identified two potentially life-bearing planets in the ultracold dwarf LP 890-9 (TOI-4306). The second was considered the most promising, the one a little further from the star, with a circulation period of 8.5 Earth days.

Although the two exoplanets are much closer to their parent star than our Mercury is to the sun, they do not experience excessive heat. Indeed, the temperature of the red dwarf itself is less than 2900 kelvins, half that of the sun. And in terms of size, it is six and a half times smaller than our native star.

Remember that astronomers still consider the Trappist-1 system (39 light years from us) to be the most encouraging. There, around an ultracold dwarf, they immediately found seven very promising planets, with large volumes of water and acceptable atmospheric indicators.

The detected objects lend themselves to observation, which can be carried out by the James Webb telescope.
