Abstract

Very-Long-Baseline Interferometry (VLBI) of non-thermal centimetric radio emission allows us to study coronal emission at sub-AU resolution in the immediate vicinity of protostars. We present first results of our VLBI observation campaign of nearby protostars, looking for compact non-thermal centimetric radio emission. Compact emission was found towards the protostellar binary YLW 15, at the position of its VLA 2 component.
