A rotating disk around the very young massive star AFGL 490.

Abstract (from CDS):

We observed the embedded, young 8-10 M_☉star AFGL 490 at subarcsecond resolution with the Plateau de Bure Interferometer (PdBI) 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 M_☉ and a radius of ∼1500 AU. A plausible explanation for the apparent asymmetry of the disk morphology is given.
