We observed the embedded, young 8--10 Msun star AFGL 490 at subarcsecond resolution with the Plateau de Bure Interferometer in the C17O (2--1) transition and found convincing evidence that AFGL 490 is surrounded by a rotating disk. Using two-dimensional modeling of the physical and chemical disk structure coupled to line radiative transfer, we constrain its basic parameters. We obtain a relatively high disk mass of 1 Msun and a radius of ~ 1500 AU. A plausible explanation for the apparent asymmetry of the disk morphology is given.

  1. GeV {\gamma}-ray emission in the low-mass star-forming region AFGL 490

    astro-ph.HE 2026-05 unverdicted novelty 6.0 of 10

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

  2. Explosive Molecular Outflows

    astro-ph.SR 2026-07 accept novelty 4.5 of 10

    Explosive molecular outflows are short-lived isotropic events in massive clusters, driven by protostellar disruptions or mergers, occurring roughly once every 140 years in the Galaxy.
