Pseudocepheids. I - R Puppis, HR 4441, HR 4511, and AI CMI
Four PC stars which are all thought to be high-mass objects, areconsidered. It is noted that R Pup and HR 4441 are apparentlyvery-high-luminosity stars for which the photometric indices areuncomplicated by photometrically unresolved companions or circumstellarmaterial. HR 4511 is seen as illustrating the effect of a close,early-type companion, and it is believed that the photometry of AI CMimay be strongly affected by circumstellar material. On the basis ofobservations of nonvariable stars covering the magnitude rangerepresented, a mean dispersion of 0.005 mag is expected in all colorindices.
