Hümmerich, Stefan
|
ASAS-SN data indicate slow variability at maximum light and a conspicuous drop in brightness at around HJD 2458000. Near- and mid-infrared properties are in agreement with an RCB classification – the star is contained in the catalogue of RCB candidates by Tisserand et al. (2012A&A...539A..51T). The SED (see attached file) is made up of two distinct blackbodies (stellar component, circumstellar shell?).
