IRAS Results for Hydrogen Deficient Stars (review)
Abstract
The Infra-Red Astronomical Satellite, working at 12 microns, 25 microns, 60 microns and 100 microns, has observed stars in several subgroups of the hydrogen deficient stars. Observations of most known R CrB stars are reported here, as well as data for several HdC stars and other carbon-rich stars, together with some intermediate helium-rich stars and related objects. Also given are LRS spectra of R CrB, RY Sgr, Upsilon Sgr, and some carbon stars. Initial reductions of the additional observations from IRAS show an extended dust shell around R CrB, and probably also around SU Tau.
