AS LMi's variability was first detected in 2013, during a search for "disappearing stars" in the [[MASTER]] database. It was initially thought to be an [[R Coronae Borealis variable]] star, although its fading was unusually slow for an R Coronae Borealis variable.<ref name="AT4784"/> Because R Coronae Borealis variables fade repeatedly, the discovery of the star's dramatic brightness decline triggered a search of archival [[Photographic_plate#Astronomy|photographic plates]] for evidence of earlier dimming events.<ref name=AT4787/><ref name=AT4788/> Tang ''et al.'' used [[Digital_Access_to_a_Sky_Century_@_Harvard|DASCH]] to search the large collection of Harvard photographic plates, and found that the star had dimmed for three years during the 1940s. They recognized that AS LMi is a very long period eclipsing binary, similar to the [[epsilon aurigae|ε Aurigae]] system.<ref name=Tang/> |

The binary system |
The binary system is comprised of an M-giant primary star orbited by a small hot secondary star that is itself surrounded by an optically thick (large [[Optical depth (astrophysics)|optical depth]]) disk.<ref name="Rodriguez"/> |
