Jets from massive protostars as gamma-ray sources: the case of IRAS 18162-2048

Abstract

Protostellar jets are present in the later stages of the stellar formation. Non-thermal radio emission has been detected from the jets and hot spots of some massive protostars, indicating the presence of relativistic electrons there. We are interested in exploring if these non-thermal particles can emit also at gamma-rays. In the present contribution we model the non-thermal emission produced in the jets associated with the massive protostar IRAS 18162-2048. We obtain that the gamma-ray emission produced in this source is detectable by the current facilities in the GeV domain.
