Upper panel: main sequence lifetimes in Gyr as a function of initial stellar mass at three different metallicities: Z_init = 0.006 (short-dashed blue line), 0.014 (continuous black line), and 0.040 (long-dashed red line). Lower panel: same as upper panel, but for the time, relative to the MS lifetime, needed to the models to cross the HR diagram from the end of the MS to the bottom of the RGB.
