Determination of extended atmospheres parameters using model grids
Abstract
In this paper we present a large set of model grids and their application for determination of wind parameters of supercritical accretion disks. The models were calculated with different radii (R ∗ = 5, 20, 40R ⊙ ), velocities (300, 600 km s ‑1 ), hydrogen abundances (20%, 40%, 50%, solar hydrogen abundance) and metallicities (Z = 0.1‑1.0Z ⊙ ) for a wide range of temperatures 16 ‑ 56 kK and mass-loss rates 10 ‑5 ‑ 10 ‑4 M ⊙ year ‑1 . We discuss algorithm for optimal model selection and validity of such models for ultraluminous X-ray sources winds.
