The Stephenson 2 star cluster also contains many … Stephenson 2 DFK 1 has been estimated to have a mass loss rate of roughly 1.35 × 10 −5 M ☉ per year, which is among the highest known for any red supergiant star. It is possible that Stephenson 2 DFK 1 underwent an extreme mass loss episode recently, due to its significant infrared excess. Visa mer Stephenson 2 DFK 1 (abbreviated to RSGC2-01), also known as Stephenson 2-18 (abbreviated to St2-18), is an enigmatic red supergiant (RSG) or possible extreme red hypergiant (RHG) star in the constellation of Visa mer When the cluster was originally discovered in 1990, Stephenson 2, and therefore Stephenson 2 DFK 1, was originally estimated to have a distance of around 30 kiloparsecs Visa mer The distance of Stephenson 2 DFK 1 has been stated to have a relative uncertainty greater than 50%, and the radius of 2,150 R☉ could possibly be an overestimation because the largest stellar radii predicted by stellar evolutionary theory is estimated to only be roughly … Visa mer The open cluster Stephenson 2 was discovered by American astronomer Charles Bruce Stephenson in 1990 in the data obtained by a deep infrared survey. The cluster is also … Visa mer Evolutionary stage RSGC2-01 shows the traits and properties of a highly luminous red supergiant, with a spectral type of M6, which is unusual for a supergiant star.
