Abstract:
The third part of the OGLE-III Catalog of Variable Stars comprises 24
906 RR Lyr stars in the Large Magellanic Cloud (LMC). This sample
consists of 17 693 fundamental-mode (RRab), 4958 first-overtone (RRc),
986 double-mode (RRd) and 1269 suspected second-overtone (RRe)
pulsators. 66 objects are foreground Galactic RR Lyr stars. The
catalog data include basic photometric and astrometric properties of
these RR Lyr stars, multi-epoch VI photometry and finding charts.
Description:
We detected one new RR Lyr star with additional eclipsing variations.
The spatial distribution of RR Lyr stars in the LMC is distinctly
non-spherical and it is elongated in the same direction as the LMC
bar. The basic statistical features of RR Lyr stars in the LMC are
provided. The apparent V-band magnitudes for RRab stars have the modal
value at 19.36mag, and for overtone RR Lyr stars it is about 19.32mag.
The mean periods for RRab, RRc and RRe stars are 0.576, 0.337 and
0.270-days, respectively.
