Abstract:
We present the largest collection of RR Lyrae stars in the Magellanic
System and in its foreground. The sample consists of 45451 RR Lyr
stars, of which 39082 were detected toward the Large Magellanic Cloud
and 6369 toward the Small Magellanic Cloud. We provide long-term
time-series photometric measurements collected during the fourth phase
of the Optical Gravitational Lensing Experiment (OGLE-IV).
We discuss several potential astrophysical applications of our
collection: investigation of the structure of the Magellanic Clouds
and the Galactic halo, studies of the globular clusters in the
Magellanic System, analysis of double-mode RR Lyr stars, and search
for RR Lyr stars in eclipsing binary systems.
Description:
The time-series photometry used in this study has been obtained with
the 1.3-m Warsaw telescope at Las Campanas Observatory (operated by
the Carnegie Institution for Science), Chile, between March 2010 and
July 2015.
