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 stellarformation. Non-thermal radio emission has been detected from the jetsand hot spots of some massive protostars, indicating the presence ofrelativistic electrons there. We are interested in exploring if thesenon-thermal particles can emit also at γ-rays. In the presentcontribution we model the non-thermal emission produced in the jetsassociated with the massive protostar IRAS 18162-2048. We obtain thatthe γ-ray emission produced in this source is detectable by thecurrent facilities in the GeV domain.
