The Doppler Footprint of Colliding Binary Winds in Emission Line Profile Shapes
Abstract
Collisions of binary winds lead to a bow shock around the star that has a weaker wind. In the large scale, the weaker wind is confined into a spiral pattern as a function of time with orbital phase. We use a model for the shape of the confined companion wind to compute line profiles as a function of the physical parameters of the system. Our model is designed to be flexible to explore the orbital effects and shock properties, which will enable us to better understand the geometries, viewing inclinations, and wind properties of massive binary systems.
