Dust structure around the Wolf-Rayet star WR104 from lunar occultation observations at 2.2µm.

Abstract (from CDS):

A rare opportunity of observing a lunar occultation of a Wolf-Rayet star (WR104) in the near-infrared K band (2.2µm) was utilized to probe the thick dust envelope surrounding the star at a high one-dimensional angular resolution (∼2mas). Analysis of the occultation light curve shows a dust structure departing significantly from the uniform disc profile. Our results are in good agreement with recent aperture-masking interferometry carried out at the Keck I telescope, which shows a pinwheel structure around WR104. We report additional fine structures in the dust envelope.
