Mass loss from the M3 supergiant HD 143183 in a young compact star cluster in Norma.
Abstract
Summary. RD 143183 is a single M 3 Ia star associated with a dozen early type stars within a radius of about one arcminute. The two most adjacent stars are more highly reddened than the rest and allow an estimate of the mass of the envelope surrounding the M star. The envelope has a radius of 0.12 pc, large enough to provide strong evidence that luminous M supergiants are able to enrich the interstellar medium with dust-like matter. A mass loss rate of 50 10-6 0/a is derived. Key words: M-supergiant circumstellar extinction mass loss star cluster
