AU Mic (red dot) in the Hertzsprung-Russell diagram. The solid coloured lines correspond to the evolutionary tracks of the PARSEC v1.25 solar metallicity models (Chen et al. 2015): masses in solar units are labelled. Isochrones with ages in the 10–50 Myr interval are shown by the dashed lines. The tracks are terminated at the age of 8.5 Gyr. The temperature and luminosity error bars of AU Mic are plotted; the luminosity error bar is smaller than the size of the symbol.
