Sample of ejecta properties for our grid of He-star explosion models. Illustration of the ejecta properties for the explosion models based on He stars evolved with the nominal mass loss rate (filled dots), a 50% enhanced mass loss rate (stars), and a 100% enhanced mass loss rate (diamond; only model he10p0x2p0 corresponds to this case). From top to bottom, we show the ejecta kinetic energy E_kin, the ejecta mass M_ej, the mean expansion rate V_m, the ⁵⁶Ni mass, the mass of the O-rich shell (loosely defined by all locations having an O mass fraction greater than 0.1), and the mass of the He-rich shell that accounts for all the mass above the O-rich shell.
