Discovery of a super-Earth near to the habitable zone of a cool starAn international team led by researchers from the IAC, using the radial velocity method, have discovered a possibly rocky planet at the edge of the habitable zone of a red dwarf star. Only a few dozen planets of this kind are known and its detection was made possible with the HARPS-N spectrograph on the Telescopio Nazionale Galileo (TNG) at the Roque de Los Muchachos Observatory, La Palma.This planet is particularly interesting because of its proximity. It is only 21 light years away, in our cosmic neighbourhood, it is one of the least massive of the known “Super-Earths”, which in addition is situated in the habitability zone of the star GJ625 (Gliese 625), a red dwarf. Even those these are the most common stars in the universe and they can host planets, we know only a few hundred of them. The majority have been discovered orbiting much more distant stars, using the transit method, in which the planet causes a minor “eclipse” when it passes in front of the star. In contrast, only a few done rocky planets have been discovered around nearby stars with the radial velocity technique, and very few have been found in their habitability zones.Read more at: www.iac.es -- source link
