Lee, T.A., and M.W. Feast, 1969: Infrared excess of RY Sgr. Astrophys. J., 157, L173-L176, doi:10.1086/180413.

A large infrared excess has been found for RY Sgr, an R CrB-type variable star. During a recent 8- month interval the visual brightness increased, while the radiation in the infrared, in the 2-3.4-μ region decreased. These observations support the general model for R CrB proposed by Stein et al., in which the infrared flux is ascribed to blackbody radiation from a circumstellar cloud of particles ejected at the time of deep minimum.
