Modelling Cygnus X-3 radio outbursts : particle injection into twin jets

Abstract

The well known X-ray binary system Cyg X-3 has exhibited several strong radio outbursts since its discovery in 1972. Their main features were initially interpreted in terms of the model of van der Laan (1966, Nat., 211), which considers synchrotron radiation from an adiabatically expanding cloud of relativistic electrons and magnetic fields. However, some discrepancies were found, particularly the maximum flux density at the higher frequencies, which was much lower than predicted
