Description
The discovery of pulsations in ultra luminous X-ray sources (ULXs) revealed a new class of neutron stars. These possibly strongly magnetized stars accrete matter at prodigious (super-Eddington) rates and are subject to very high spin-up torques. Other classes of sources such as the Z sources (e.g., Sco X-1) have accretion disks radiating at nearly Eddington luminosity. Recent computing advances allow for the first time to include radiation in magnetohydrodynamic simulations of accretion flows in general relativity. I will present radiative GRMHD simulations of accretion disks and discuss their relevance to neutron star sources.
