The search for terrestrial like exoplanets in the habitable zone of their stars is one of the most significant areas of exoplanetary science. The habitable zone is defined as the region around a given star where rocky planets are within the suitable temperature range to potentially support liquid water on their surfaces. Earth-like planets within habitable zones are therefore the
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
