Benchmarking Differential Reddening in Front of Globular Clusters
The Astronomical JournalInterstellar extinction is a major obstacle in determining accurate stellar parameters from photometry near the Galactic disk. It is especially true for globular clusters at low galactic latitudes, which suffer from significant amounts of spatially ...

Adding RR Lyrae y-Band Template Light Curves to gatspy
The Astronomical JournalWe complement the y -band template light curves for RR Lyrae to the well-established template light curves in the ugriz-band, where the latter have been adopted in the astroML/gatspy python package as one of the period-search methods for RR Lyrae.

Discovery of RR Lyrae in the Ultra-faint-dwarf Galaxy Virgo III
The Astronomical JournalVirgo III is a newly discovered ultra-faint-dwarf (UFD) candidate, and finding RR Lyrae associated with this galaxy is important to constrain its distance.

The impact of large-scale, long-term optical surveys on pulsating star research
EPJ Web of Conferences, 2017 The era of large-scale photometric variability surveys began a quarter of a century ago, when three microlensing projects - EROS, MACHO, and OGLE - started their operation.

RW Arietis; an RR Lyrae Variable Star in an Eclipsing System [PDF]
International Astronomical Union Colloquium, 1971 AbstractRW Arietis was observed photoelectrically in the UBV-system during fall and winter 1966 with the 70 cm telescope at the Lunar and Planetary Laboratory Catalina station, University of Arizona, Tucson, on 19 nights. Peculiar variations of the usually stable RRc light curve observed on three nights can be interpreted as a superposition of the RR ...

Variable stars in galactic globular clusters
Astronomy & AstrophysicsWe present a comprehensive catalog of 2824 RR Lyrae stars (RRLs) residing in 115 Galactic globular clusters (GCs). Our catalog includes 1594 fundamental-mode (RRab), 824 first-overtone (RRc), and 28 double-mode (RRd) RRLs, as well as 378 RRLs of an unknown pulsation mode. We cross-matched 481 349 RRLs reported in the third Data Release (DR3) of the ESA

Classification for 969 Double-mode RR Lyrae Stars from Zwicky Transient Facility
The Astrophysical Journal Supplement SeriesRR Lyrae (RRL) variable stars are cornerstone distance indicators. In particular, double-mode RR Lyrae (RRd) stars enable period–luminosity relations (PLRs) that are less sensitive to metallicity, reducing systematic biases in distance measurements ...
