Modelling optical emission of Ultra-luminous X-ray Sources accreting above the Eddington limit
We study the evolution of binary systems of ultraluminous X-ray sources and compute their optical emission assuming accretion onto a black hole via a non-standard, advection-dominated slim disc with an outflow. We consider systems with black holes of 20–|$100\, \mathrm{M}_{\odot }$|, and donor masses between 8 and |$25\, \mathrm{M}_{\odot }$|. …
