R85
Candidate luminous variable star in the constellation Dorado / From Wikipedia, the free encyclopedia
R85 (or RMC 85, after the Radcliffe Observatory Magellanic Clouds catalog[5]) is a candidate luminous blue variable[9] located in the LH-41 OB association[10] in the Large Magellanic Cloud.

R85 has been shown to vary erratically in brightness with an amplitude of about 0.3 magnitudes. It shows variations on several timescales, sometimes with a distinct 400 day period. It has also shown temperature changes associated with brightness changes over several years, a characteristic of luminous blue variables.[12]
Based on R85's current properties and evolutionary models, it probably started out with an initial mass of 28 M☉.[10] It is theorized to be making a bubble known as DEM L132a with its stellar wind in the nebula LHA-120 N119, along with S Doradus.[13] It has an infrared excess consistent with a stellar wind contribution.[4]
