Circumstellar dust in the vicinity of luminous blue variables.
Abstract
16 luminous blue variables (LBV) and related stars are identified as IRAS Point Source Catalogue Objects, 13 of them having far-infrared excesses. The excesses are interpreted as cold dust in the vicinity of LBV. In the framework of the symmetric sphere dust model the diameters of the shells are found using the Blackwell-Shallis method. They turned out to be equal to some thousands of photospheric radii (5×10-2 - 10-3pc).
