Density distributions of all gas material as a function of the explosion time in the impact simulations for a G/K-dwarf companion model (M₂ = 0.9 M_⊙) with a binary separation of 5.48 R_⊙ (=7.1R₂). The direction of motion of the incoming SN shell front is from right to left (see arrow symbols). The impact is initiated at t ≈ 100s after the explosion. The color scale shows the logarithm of the mass density in g cm^-3.
