Beamed emission from a neutron-star ULX in a GRRMHD simulation
arXiv:2107.01149 · doi:10.3847/2041-8213/ac1859
Abstract
We perform a global 2.5D general-relativistic radiation magnetohydrodynamic simulation of super-critical accretion onto a neutron star with a G dipolar magnetic field, as a model of a neutron-star-powered ultraluminous X-ray source (ULX). We compute a lower limit on the total luminosity of , and find the radiation to be highly beamed by the accretion disk outflows. The apparent isotropic luminosity, which is a function of the viewing angle, reaches a maximum above , consistent with the luminosities observed in ULXs.
