Pulsating stars in ω Centauri. Near-IR properties and period-luminosity relations
EPJ Web of Conferences, 2017 ω Centauri (NGC 5139) contains many variable stars of different types, including the pulsating type II Cepheids, RR Lyrae and SX Phoenicis stars. We carried out a deep, wide-field, near-infrared (IR) variability survey of ω Cen, using the VISTA telescope.

RADIATIVE TRANSFER EFFECTS ON THE COLORS OF RR LYRAE STARS
Odessa Astronomical Publications, 2017 The methods of Davis and Cox (1980), are applied to a series of models described by Bono and Stellingwerf (1994) to deter-mine the colors of RR Lyrae stars.

Variability in NGC 3201 Giant Stars
The Astronomical Journal, 2023 We present the analysis of 510 light curves in V and I bands of 255 giant stars in the globular cluster NGC 3201. Our aim is to expand the sample of new types of variables reported in a previous study. These variables show a short period ( P _V < 0.6 day)

The double‐mode RR Lyrae variable BS Com [PDF]
Astronomische Nachrichten, 2007 AbstractWe present the frequency analysis of the multicolour time series photometry of the field RRd variable BS Comae. The large number of data points in each of the BV (RI)C bands and the ∼0.01 magnitude accuracy of the individual measurements allow us a high precision analysis of the properties of the combination frequencies due to nonlinear ...

Pulsation Properties of Blazhko and Non-Blazhko RRab Stars
The Astrophysical Journal Supplement SeriesIn this study, we conduct a comparative analysis of the properties of Blazhko and non-Blazhko RRab stars. We identified 1054 non-Blazhko and 785 Blazhko RRab stars in the photometric data observed by the K2 mission, which, combined with those 37 stars ...

The RR Lyrae Luminosity Metallicity Relation Revisited
The Astronomical JournalWe utilize a set of internally consistent absolute ages for a sample of ten Galactic globular clusters to determine the variation of the slope with the zero point of the M _V (RR) ∼ [Fe/H] relation for RR Lyrae variables.

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.
