Comparison of different profiles of donor and runaway, and the resulting heating. From top to bottom: first panel Density profiles of the donor (blue) and runaway star (orange). Second panel: Temperature profiles of the donor and the runaway. Third panel: Entropy profiles of the donor and the runaway. Fourth panel: Non-adiabatic heating done after the ejecta hits. Fifth panel: Mass fractions of ¹²C (similar to ¹⁶O), ⁴He, and ⁵⁶Ni. The mass coordinates, given in solar masses, are shown until the donor mass of 0.661 M_⊙, as outside of this mass range the entropy difference is not defined. The dashed black line represents the mass coordinate where ¹²C and ¹⁶O mass fractions become less than 90% of the total mass fraction. The solid black line shows where the surface cut as defined in Section 2.2.1 is done. The grey portion for helium marks what we remove in our standard models.
