Notes. T_eff is the effective temperature; L_★, the luminosity; M_★, the mass; R_★, the radius; and ν sin(i), the projected rotational velocity. R′_HK is an activity indicator defined as $F_{\text{HK}}^{\prime }/\sigma T_{\text{eff}}^4$, where F′_HK is the chromospheric flux in the H and K lines of Ca II. The estimated age of the star is, however, uncertain as it depends on the method used (see discussion in Sect. 4). References: (1) Gaia Collaboration (2016, 2023); (2) Montesinos et al.
