High Energy Emission Processes from Normal Stars and Stellar Clusters
Abstract
In this talk I will review the emission processes that can generate high energy emission from normal stars, with a focus on stars that have been observed with FERMI and NUSTAR, as well as ground-based Cerenkov telescopes (HESS, VERITAS, MAGIC).I will discuss colliding stellar winds and other relevant interactions in primarily massive stars (shocks/B-fields etc), and then discuss the various processes that contribute to (or indeed inhibit) high energy emission from such stars. The connection with other wavelengths (notably non-thermal radio emission) will also be discussed.I will extend this discussion to include emission from very young and massive stellar clusters (eg Westerlund 2) and potential emission from bow-shocks around runaway stars, as well as touching on high energy emission from lower mass stars.
