The bow shock produced by the high-mass runaway star BD +43° 3654 (Comerón & Pasquali 2007) has been detected as a non-thermal radio source (S_ν ∝ ν^{-α}, =0.5) and it is the first one of that type ever observed (Benaglia et al. 2010). The non-thermal detection provides evidence of the presence of a magnetic field and relativistic electrons. This population of relativistic particles can produce high-energy (HE) emission.
