TL;DR
This paper models the non-thermal radio emission from colliding-wind binary systems Cyg OB2 No. 8A and No. 9, explaining how shock-induced electron acceleration produces observable synchrotron radiation.
Contribution
It introduces a detailed model of non-thermal radio emission specifically for the colliding-wind binaries Cyg OB2 No. 8A and No. 9, advancing understanding of their emission mechanisms.
Findings
Successful modeling of radio emission in Cyg OB2 No. 8A and No. 9
Identification of shock acceleration as key to non-thermal emission
Insights into electron acceleration processes in stellar wind collisions
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.
