Density plot in logarithmic scale of the final remnants after the interaction has ceased. The dashed lines represent the location of the secondary star. As mentioned before, the companion in model RN1 is a red giant of ∼110 R_⊙. Due to the orbital characteristics and accretion rate adopted in model RN2, the best fit for the companion is a subgiant between 4 and 6 R_⊙. In our case we decided to use a 1 M_⊙ and 5.23 R_⊙ star so that the system shared the same geometric proportions as in model RN1. In the case of the CN and SN Ia models the companion is a Sun-like main-sequence star with 1 R_⊙ and 1 M_⊙.
