Runaway stars and the formation of bow shocks

Stellar winds are ubiquitous and one of the primary channels through which stars lose mass and return nuclear enriched material to galaxies. For runaway stars moving supersonically through the interstellar medium (ISM), the collision of the stellar wind with the surrounding gas produces an arc-like structure called a bow shock. Using relatively simple physics, bow shocks can be powerful probes of properties of the ISM, stellar winds and dynamics. In this project, the latest and most detailed hydrodynamic and radiative transfer codes will be used to investigate the formation of bow shocks, comparing the models with high-resolution observations.
