Claims

C1strongest claim

the protostellar jet driven by AFGL 490 is identified as a plausible site for particle acceleration, and the derived timescales and maximum particle energies are consistent with theoretical predictions for such jets.

C2weakest assumption

Energetic arguments rule out stellar winds as the primary accelerator. This premise assumes that wind power, mass-loss rates, and acceleration efficiency have been estimated accurately enough to exclude them, which if underestimated could reopen winds as a viable source.

C3one line summary

Discovery of extended GeV gamma-ray emission from AFGL 490, with the protostellar jet identified as the likely particle accelerator rather than stellar winds.
