Evolutionary tracks for models with varying mass and solar metallicity plotted in a variation of a classic H-R diagram (Δν plotted against T_eff). The star shows the location of the Sun and the different line colours represent different masses starting with the black 0.7 M_⊙ line on the far right going in increments of 0.1 M_⊙ to the blue 1.6 M_⊙ line on the far left.
