The serendipitous discovery of a stellar ring at mid-infrared wavelengths.

PHILLIPS J.P. and RAMOS-LARIOS G.

Abstract (from CDS):

We present images and photometry of a stellar ring-like structure G052.4-00.0 discovered during visual inspection of the Spitzer GLIMPSE Atlas. Although G052.4-00.0 may correspond to one of a large variety of sources, it is argued that it is most likely to be associated with an early-type supergiant at a distance of ∼8 kpc from the Sun. Where this is the case, then the radius of the ring would be of the order of ~0.3 pc, comparable to those of similar structures about other supergiant stars, and the extinction AV would be of the order of ∼21 mag.
