Abstract:
The fifth part of the OGLE-III Catalog of Variable Stars presents 23 R
CrB (RCB) stars in the Large Magellanic Cloud (LMC). 17 of these
objects have been spectroscopically confirmed by previous studies,
while 6 stars are new candidates for RCB variables. We publish the VI
multi-epoch OGLE photometry for all objects.
Description:
We use the sample of carbon-rich long-period variables released in the
previous part of this catalog to select objects with severe drops in
luminosity, i.e., with the DY-Per-like light curves. DY Per stars are
often related to R CrB variables. We detect at least 600 candidates
for DY Per stars, mostly among dust enshrouded giants. We notice that
our candidate DY Per stars form a continuity with other carbon-rich
long-period variables, so it seems that DY Per stars do not constitute
a separate group of variable stars.
