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.
