Notes. The methods used to obtain the stellar parameters are described in the text. The stellar luminosity L_★ is computed following the Stefan-Boltzmann law and using the Stefan-Boltzmann constant σ_SB. ⁽¹⁾SIMBAD astronomical database from the Centre de Données astronomiques de Strasbourg (http://simbad.u-strasbg.fr/simbad/). ⁽²⁾Archive of the Gaia mission of the European Space Agency (https://gea.esac.esa.int/archive/).
