HD 96446 in the log T_eff–log g plane. Our solution (black dot) is compared to previous atmospheric parameter determinations reported in the literature: Hunger & Groote (1999, box), Zboril et al. (1997, circles), Zboril & North (2000, triangle), and Neiner et al. (2012a, diamond). Where available, 1σ error bars are shown. Overlayed are Geneva evolution tracks for rotating stars, computed for metallicity Z = 0.014 and an initial value of 40% of the critical rotation rate (Ekström et al. 2012, full lines). Corresponding isochrones for log τ(Myr) = 7.2, 7.3, and 7.4 are also shown (dotted lines, from left to right), and the position of the zero age main sequence (long dashed line).
