Position of 78 Vir in the Hertzsprung-Russell diagram. The constraints on the fundamental parameters are indicated by the 1σ-error box (log (Teff), log (L/L⊙)) and the diagonal lines (radius). The blue box in solid lines corresponds to our work and the black box in dashed lines to the parameters derived by Khalack & Wade (2006). Isochrones are overplotted in green lines for Z = 0.019, Y = 0.28242, [M/H] = 0.119 and ages of 435 Myr (best fit – dashed line), 380 Myr, and 490 Myr (dash-dotted lines).
