Absolute magnitude in V-band versus effective temperature diagram for HIP 65426 and stars within 5°  with similar distance and kinematics. Blue circles: HIP 65426 and two stars with space velocity difference smaller than 3 km s^-1. Red circles: stars with space velocity difference with respect to HIP 65426 between 3 and 10 km s^-1. Empty circles: stars with space velocity difference larger than 10 km s^-1. The 5, 12, 20, 30, 70 Myr solar-metallicity isochrones by Bressan et al. (2012) are overplotted and labeled individually.
