摘要：
R CrB stars form a family of highly hydrogen deficient, late-type stars, which undergo deep minima in their visible light curve at irregular intervals. We present spectra of R CrB itself, observed at different times after minimum, and of RY Sgr, For this workshop paper we concentrate on the technical feasibility and problematics of the calibration of such variable measurements using PHT-S on ISOPHOT.
