Description
Massive stars launch hypersonic winds that generate strong shocks in the interstellar medium. In the case of runaway stars with supersonic peculiar velocities, the resulting shock structure forms a distinctive bow shape, known as a bowshock. Within these shocks, the material heats up and compresses, producing free-free radiation, while also relativistic particles are accelerated, leading to synchrotron radiation. I will present an overview of the observational status of stellar bow shocks in radio so far, theoretical predictions of their emission, and future prospects for studying these radio sources with the SKA.
