VY Car, S Nor and photometric luminosities for bright giants and supergiants of types G and K.
Abstract
Observations in the modified Stromgren system of the Cepheids VY Carinae and S Normae with their associated early-type stars are discussed. The luminosities of the Cepheids, together with the bright giants R Puppis, HR 2834, HR 4180, and HDE 269953 in the Large Magellanic Cloud (LMC), are used for calibration of photometric luminosities.
