An international scientific team, with the participation of the Instituto de Astrofísica de Andalucía (IAA-CSIC), has measured with unprecedented precision the mass and radius of Gliese 486 b, a "super-Earth" type exoplanet, discovered in 2021 with the CARMENES instrument at Calar Alto observatory.
Its detailed study has allowed, for the first time, to make solid predictions about the structure and internal composition of a super-Earth.
