A system of super-Earth exoplanets orbiting around GJ 3998 described in the paper: “HADES RV Programme with HARPS-N at TNG XVI. A super-Earth in the habitable zone of the GJ 3998 multi-planet system” of A. K. Stefanov (IAC)

At just 60 light-years away from us, the M-type star GJ 3998 hosts a system of three super-Earths, discovered and studied thanks to observations from the Telescopio Nazionale Galileo.   M-type stars are among the most important targets in the search for exoplanets, primarily for two reasons: they are the most numerous stars in our Galaxy, and the most commonly

Low mass star (in particular M-type star, with a mass between 0.075 and 0.5 solar masses) are typical targets for the search and study of exoplanets. In these stars, in fact, the radial velocity method is more efficient than in stars with higher mass. Radial velocity consists in detecting periodic oscillations in the stellar spectra due to the motion of
