Post-impact 1D angle-averaged profiles (thin lines) of specific internal energy, ℰ_int (top panel) and density, ρ (bottom panel) as functions of fractional mass coordinates at the end of the SPH impact simulation for our reference model, Model A. For a comparison, the relaxed starting models in MESA are shown as thick lines. The results for the impact simulation with or without binary orbital motion and stellar spin taken into account are shown as dash-dotted lines and solid lines, respectively.
