Dependence of the explodability parameters ξ_2.5, s_c, μ₄M₄ and μ₄ of single and binary-stripped stars (Case A, Case Be, Case Bl and Case C donors) on M_CO at Z = Z_⊙ and at Z = Z_⊙/10. To obtain these, the data points (circles) from S21 and S23 have been fitted using GPR models (solid lines). The red vertical lines indicate the lower (upper) threshold in M_CO below (beyond) which only successful (failed) SNe occur, while the red horizontal lines indicate the lower and upper thresholds in ξ_2.5, μ₄M₄ and s_c, respectively. The background colors show the resulting final fate classification based on a single explodability parameter: successful SNe (yellow), failed SNe (brown) and unclassified (blank).
