Abstract

The nucleosynthesis of heavy elements in the scenario for the evolution of a close binary of neutron stars differing greatly in mass is considered. In contrast to the scenario for the merger of two neutron stars of comparable masses considered repeatedly in the literature, the evolution of such a binary at the final stage consists in a rapid mass transfer to the more massive star and an explosive disruption of the low-mass component. We provide the details of the explosion and calculate the abundances of the heavy elements produced in this process for various initial conditions.

低质量中子星在密闭双星爆炸过程中重元素的产生

摘要

考虑在质量差异很大的中子星紧密双星的演化过程中，重元素的核合成。与文献中反复考虑的两个质量相当的中子星合并的情况相反，这种双星在最后阶段的演化在于将质量快速转移到质量更大的恒星中，并对低质量的恒星进行爆炸性破坏。质量分量。我们提供了爆炸的详细信息，并针对各种初始条件计算了此过程中产生的重元素的丰度。
