Low-mass neutron star nucleosynthesis — stripping scenario

Year: 2024

Type: article

Abstract: 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. The number of heavy elements produced in a low-mass neutron star crust during the explosion is approximately 0.041 [Formula: see text], which exceeds the number of heavy elements ejected as jets in the neutron star merger scenario.
