英文摘要	The core-degenerate (CD) scenario has been suggested to be a possible progenitor model of type Ia supernovae (SNe Ia), in which a carbon-oxygen white dwarf merges with the hot CO core of a massive asymptotic giant branch star during their common-envelope phase. However, the SN Ia birthrates for this scenario are still uncertain. We conducted a detailed investigation into the CD scenario and then gave the birthrates for this scenario using a detailed Monte Carlo binary population synthesis approach. We found that the delay times of SNe Ia from this scenario are similar to 70Myr-1400Myr, whichmeans that the CD scenario contributes to young SN Ia populations. The Galactic SN Ia birthrates for this scenario are in the range of similar to 7.4x10(-5) yr(-1) - 3.7 x 10(-4) yr(-1), which roughly accounts for similar to 2%-10% of all SNe Ia. This indicates that, under the assumptions made here, the CD scenario only contributes a small portion of all SNe Ia, which is not consistent with the results of Ilkov & Soker.
