The effects of mass loss (η = 0.6) on evolutionary tracks of high (Z = 0.014, left panel) intermediate (Z = 0.004, middle panel), and low (Z = 0.0014, right panel) metallicity. The models include overshooting both from the MS core and envelope (O24_ML6 models). Tracks are color coded according to a fraction of mass lost, ΔM. Tracks without mass loss (O24) are plotted with dashed black lines for reference.
