Distribution of mass ejected per H nova eruption, Z = 10⁻³. Top panels count the number of events in each bin while the bottom panels track the ejecta mass in each bin. Coloured according to the WD’s composition (left) and the donor stellar type (Hurley et al. 2000, 2002). The donor stellar types are, in descending order: low-mass main sequence stars, main sequence stars, Hertzsprung Gap stars, first-ascent giant branch stars, core He burning stars, early asymptotic giant branch stars, and thermally pulsing asymptotic giant branch stars.
