Investigating the X-ray emission from the massive WR+O binary WR 22 using 3D hydrodynamical models

Parkin, Elliott; Gosset, E


Aims. We examine the dependence of the wind-wind collision and subsequent X-ray emission from the massive WR+O star binary WR 22 on the acceleration of the stellar winds, radiative cooling, and orbital motion. Methods. Three dimensional (3D) adaptive-mesh refinement (AMR) simulations are presented that include radiative driving, gravity, optically-thin radiative cooling, and orbital motion. Simulations were performed with instantaneously accelerated and radiatively driven stellar winds....[Show more]
