X-ray lines from accreting black holes.
Abstract
The X-ray emission line spectrum of black holes surrounded by accretion disks is considered. For steady-state disks, we calculate the expected line strengths, equivalent widths and broadening. This is done for the L-alpha line of S(15+), using a representative set of disk parameters, and for the intercombination and forbidden lines of Fe(24+), for a range of disk parameter. The values predicted differ from those of other models of X-ray sources, and are such that experimental detection appears feasible.
