Abstract

Context. LS 5039 is an X-ray binary that presents non-thermal radio emission. The radiation at ~5 GHz is quite steady and optically thin, consisting of a dominant core plus an extended jet-like structure. There is a spectral turnover around 1 GHz, and evidence of variability on timescales of 1 yr at 234 MHz.
