摘要

本文研究了一颗低质量中子星外壳中的核合成过程,该中子星外壳在一个近双星系统中由于吸积而失去质量,并在达到流体力学不稳定构型时发生爆炸。r-过程主要在内壳中进行。外壳的核合成是一个爆炸过程,由向外传播的冲击波引起温度急剧上升(冲击波核合成)。爆炸过程中在低质量中子星外壳中产生的重元素数量约等于 0.041 个太阳质量,超过了中子星合并情景中作为喷流喷出的重元素数量。

Low-mass neutron star nucleosynthesis -- stripping scenario
This paper examines nucleosynthesis in a low-mass neutron star crust that loses mass due to accretion in a close binary system and, reaching a hydrodynamically unstable configuration explodes. The r-process proceeds mainly in the inner crust. Nucleosynthesis in the outer crust is an explosive process with a sharp increase in temperature caused by an outward-propagating shockwave (shock-wave nucleosynthesis). The number of heavy elements produced in a low-mass neutron star crust during the explosion is approximately equals 0.041 solar masses, which exceeds the number of heavy elements ejected as jets in the neutron star merger scenario.
