Determination of the Parameters of ULXs with Model Grids of Extended Atmospheres
Abstract
In current work we continued study of wind parameters of ultraluminous X-ray sources (ULXs) using model grids of extended atmospheres. We present sets of models with temperatures from 18000 up to 56000 K as a line equivalent widths (EWs) and their ratios diagrams. The fundamental wind parameters for some spectrally studied ULXs were estimated using EW diagrams. Also, influence of the wind velocity law on the equivalent widths of observed emission lines was investigated.
