A super-Earth for the star GJ 9689. The study: “HADES RV programme with HARPS-N at TNG. XIV. A candidate super-Earth orbiting the M-dwarf GJ 9689 with a period close to half the stellar rotation period” of J. Maldonado (INAF-OAPA) recently appeared on A&A

M stars are the most common stars in the Universe. They have a mass ranging between 0.6 and 0.08 Solar masses in the main sequence, and an effective temperature ranging between 3900 K and 2400 K. In these stars, the signals due to the presence of planets, such as radial velocity (periodic oscillations of the star from its rest position

A super-Earth for the star GJ 740. The study: “A super-Earth on a close-in orbit around the M1V star GJ 740. A HADES and CARMENES collaboration” of B. Toledo-Padrón (IAC) recently appeared on Astronomy & Astrophysics

In the last years, stars of spectral class M (which are stars with effective temperatures between 2400 and 3700 K and masses between 0.08 and 0.45 solar masses) have been extensively observed for the search of exoplanets. This both because they are the most abundant class of stars in the Galaxy, and because the low star/planet mass ratio, compared to

A caccia di pianeti extra solari con Laura Affer alla Feltrinelli

Domenica 5 febbraio alle ore 11, alla libreria La Feltrinelli, numerosi bambini hanno partecipato al laboratorio Astrokids “A caccia di pianeti extra solari”, imparando come vengono scoperti i pianeti che orbitano attorno ad altre stelle, che caratteristiche possa avere un pianeta extra solare e cosa voglia dire zona abitabile. A guidarli in queste interessanti scoperte un’ospite d’eccellenza, l’astronomo Laura Affer dell’INAF
