Non-thermal radio emission from colliding-wind binaries: modelling Cyg OB2 No. 8A and No. 9

High Energy Astrophysical Phenomena 2015-05-20 v1

Abstract

Some OB stars show variable non-thermal radio emission. The non-thermal emission is due to synchrotron radiation that is emitted by electrons accelerated to high energies. The electron acceleration occurs at strong shocks created by the collision of radiatively-driven stellar winds in binary systems. Here we present results of our modelling of two colliding wind systems: Cyg OB2 No. 8A and Cyg OB2 No. 9.
