When the star has powerful winds the interaction of the wind with the interstellar material produces a system of shocks. The outer shock, called the bow shock, propagates through the ambient medium cooling efficiently and compressing the gas. The bow shock of a massive runaway star was detected at radio wavelengths with a high level of non-thermal emission, most probably synchrotron radiation. This type of emission is intrinsically highly polarized. In this talk I will present a model of the bow shock structure of massive runaway stars, aiming to produce theoretical synchrotron polarization maps. I will also discuss the case of BD+43\u00b03654, which was recently observed at radio but no polarization was detected.  <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Lunes 18 de octubre de 2021 &#8211; 13:30 horas Expositora: Mar\u00eda Victoria del Valle, IAG, USP Resumen: Runaway stars move through the interstellar medium with V > 30 km\/s.
