Total removed companion mass (ΔM₂, in a unit of M₂) as a function of the SN explosion energy for our 0.9M_⊙ G/K-dwarf companion model. All parameters except the SN explosion energy are kept constant, meaning that we only change the SN explosion energy according to Eqs. (1) and (2). Thus, for a fixed initial binary separation of 5.48 R_⊙ (2 a_min) and a total ejecta mass of 1.4 M_⊙, different SN explosion energies of (1.0, 4.0, 6.0, 8.0) × 10⁵¹ erg are investigated. The fitting function and fitting parameters are also shown.
