Best-fitting 1D CE simulation for q = 0.25 when comparing to the 3D CE simulation of Sand et al. (2020). Full lines show the orbital separation, and the dotted and dash-dotted lines show the mass fraction of ejected envelope f_ej and f_ej, all, respectively. The results of the 3D simulations are shown in orange, and the results from this work are shown in blue. The vertical dashed gray line indicates the end of the dynamical plunge-in phase as determined by Eq. (22). The 3D simulation results are all shifted by Δt_min = −58 d to compensate for the difference in the initial separation. The gray shaded region shows t < 0 d, for which we cannot compare the 1D simulation to the 3D simulation.
