An international team of scientists, supervised by the German University of Cologne, discovered that the stellar flares of the star TRAPPIST-1can heat up outer planets around it, providing a habitable environment RT.
Journal suggests Astrophysical Journal Lettersuntil TRAPPIST-1 planetary system outside Solar SystemIt is located 39 light-years from Earth and consists of a red dwarf M-dwarf And seven outer rocky planets, which might be habitable, revolve in smaller orbits than in the solar system. Red dwarfs are the most widespread type of star, but they emit much less light radiation than the sun.
It became clear to the researchers from the test result whether the heat emitted from TRAPPIST-1 Sufficient to support processes that might create an environment conducive to life, that heating the planets with the help of Ohmic dissipation of stellar energy, is sufficient to stimulate geological activity in the long term, which allows the development of the surface environment to be habitable or subject it to a series of conditions favorable to the emergence of life.
Ohmic dissipation is the conversion of electrical energy into heat due to the resistance of a conductor TRAPPIST-1 Coronal mass emissions carry magnetic currents, and the dissipation of this energy heats the nuclei of the planets, which stimulates volcanic activity and the emission of gases, which leads to the formation of a thick layer in the atmosphere that reduces the effect of flares on the surface of the planets.
