High Energy Processes in Wolf-Rayet Stars

Solar and Stellar Astrophysics 2019-04-10 v1 High Energy Astrophysical Phenomena

Abstract

Wolf-Rayet (WR) stars are massive (\geq10 M_{\odot}) evolved stars undergoing advanced nuclear burning in their cores, rapidly approaching the end of their lives as supernovae. Their powerful winds enrich the interstellar medium with heavy elements, providing raw material for future generations of stars. We briefly summarize high-energy processes in WR stars, focusing mainly on their X-ray emission. We present new results from Chandra observations of the eclipsing WR+O binary CQ Cep covering a full orbit which stringently test X-ray emission models.
