A model for a photoionized, conical jet from a young, massive star

Supersize me! Jets from massive young stellar objects

“…The presence of massive disks must thus play a fundamental role in shielding and launching them. Additionally, an important role could be played by the high density at the base of the jet, which might trap the stellar ionising radiation, so that the jet beam is neutral at larger distances (Raga et al 2017). The structure of massive jets close to source might then resemble an onion-like structure, with an ionised base and core plus layers of neutral atomic, and (possibly) molecular gas.…”
