Mass distribution with metallicity in two samples of dwarf MS stars (top panel) and early RGB stars (bottom panel) selected from the GALAH catalogue. The left panels zoom in on the low-mass and metal-poor area. The right panels show the whole sample. The empirical relations at two regions of [Fe/H] are shown as red and orange solid lines. The black horizontal line indicates the mass limit 0.94M_⊙, while the vertical lines indicate the metallicity [Fe/H] = -0.85 and -0.65.
