WR 140 in the Infrared
arXiv:1101.1046
Abstract
Observations in the infrared have played a significant role in the development of our understanding of WR140. Two sets of observations are described here: the changing profile of the 1.083-μm He I line observed for the 2009 campaign to study evolution of the wind-collision region near periastron passage, and multiwavelength photometry and imaging of the dust made by WR140 in previous periastron passages.
