The R Coronae Borealis Type Variables (review)
Abstract
A general review of the RCB stars is given. The available observations (spectra, photometry (including infrared) and polarization) seem most easily explained by a model in which a cloud of dust is ejected towards the observer at times of deep minima. The large radius changes in the pulsation cycle of RY Sgr suggest a high luminosity. This is also indicated by the RCB stars in the LMC. Theoretical work on RCB stars is briefly reviewed. The possible relation of the variables to the planetary nebulae and the novae is mentioned.
