Astronomers have discovered a new exoplanet 70 light-years from the Sun. A preprint of an article on this is available at arXiv.org.
Located in the red dwarf system K2-415, the planet was named K2-415b. The discovery was made with the help of Kepler and TESS telescopes by the transit method – analyzing the dynamics of the star’s brightness, which decreases when the planet eclipses the stellar disk.
Observations have shown that K2-415b has a radius of about 1,015 Earth radii and a mass of about three Earth masses. The planet orbits its parent star at a distance of about 0.027 AU every 4,018 days. from him. One astronomical unit is equal to the distance from the Earth to the Sun. The equilibrium temperature of K2-415b is estimated to be around 400 Kelvin, making it a very hot planet.
The main star K2-415 belongs to the spectral class M5V and has an effective temperature of 3173 K. The radius of the star is about 0.2 of the radius of the Sun, and its mass is 0.16 times the mass of the Sun.
The study’s authors, from Japan’s SOKENDAI University, believe the planet they described is a promising target for further research, including attempts to determine the presence and composition of the atmosphere using a spectrometer telescope.
