Ages of primary (τ_A) and secondary (τ_B) stars determined from dynamical masses, dynamical radii and (if available) projected rotational velocities vsini. The colour coding indicates the mass ratios of secondary (M_B) to primary (M_A) stars. Squares and filled circles show binaries for which vsini measurements are available and are lacking to derive stellar ages, respectively. The bottom panel is a zoom into the age range 0 − 12.5 Myr of the top panel.
