本文利用一种直接方法,从当前观测获得的具有个体分布的质量值样本中估计分布函数,分析了 Wolf-Rayet 恒星与黑洞质量分布的形式及其关系。结果表明,考虑到 WR 恒星在该演化阶段结束时的质量损失,黑洞的质量分布接近于引力坍缩前 WR 恒星 CO 核的质量分布,即 $M_\mathrm{BH}\simeq M_\mathrm{CO}$。
英文摘要
The form and relationship between the mass distributions of Wolf-Rayet stars and black holes are analyzed using a direct method for estimating the distribution function from a sample of mass values with individual distributions obtained from current observations. It is shown that, taking into account the mass loss of WR stars by the end of this evolutionary stage, the mass distribution of black holes is close to that of the CO-cores of WR stars before gravitational collapse, $M_\mathrm{BH}\simeq M_\mathrm{CO}$.
