A Catalogue of RR Lyrae Stars from the Northern Sky Variability Survey [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2006
A search for RR Lyrae stars has been conducted in the publicly available data of the Northern Sky Variability Survey (NSVS). Candidates have been selected by the statistical properties of their variation; the standard deviation, skewness and kurtosis ...

Rr Lyrae Variable Stars [PDF]

open access: bronzeHighlights of Astronomy, 1980
Some twenty years have passed since the decision was taken by the General Assembly of IAU in 1958 to resume a regular control of light variation stability in RR Lyrae stars. With this end in view the revision of elements is carried out at the Odessa Astronomical Observatory yearly, whereas ephemerides of RR Lyrae stars are published at the Krakov ...

Infrared K-band Photometry of Field RR Lyrae Variable Stars [PDF]

open access: bronzeThe Astronomical Journal, 2019
We present multi-epoch infrared photometry in the $K_s$-band for 74 bright RR Lyrae variable stars tied directly to the 2MASS photometric system. We systematize additional $K$-band photometry from the literature to the 2MASS system and combine it to obtain photometry for 146 RR Lyrae stars on a consistent, modern system.

THE CHEMICAL COMPOSITIONS OF VARIABLE FIELD HORIZONTAL-BRANCH STARS: RR LYRAE STARS [PDF]

open access: bronzeThe Astrophysical Journal Supplement Series, 2011
We present a detailed abundance study of 11 RR Lyrae ab-type variables: AS Vir, BS Aps, CD Vel, DT Hya, RV Oct, TY Gru, UV Oct, V1645 Sgr, WY Ant, XZ Aps, and Z Mic.High resolution and high S/N echelle spectra of these variables were obtained with 2.5 m du Pont telescope at the Las Campanas Observatory.

Nonradial modes in RR Lyrae stars from the OGLE Collection of Variable Stars [PDF]

open access: green, 2016
The Optical Gravitational Lensing Experiment (OGLE) is a great source of top-quality photometry of classical pulsators. Collection of variable stars from the fourth part of the project contains more than 38 000 RR Lyrae stars. These stars pulsate mostly in the radial fundamental mode (RRab), in radial first overtone (RRc) or in both modes ...

RR Lyrae Variable Stars in the Dwarf Spheroidal Galaxy Leo I [PDF]

open access: bronzeThe Astrophysical Journal, 2001
We report the discovery of a significant population of RR Lyrae variables in the dwarf spheroidal galaxy Leo I. Based on 40 V and 22 B images of the galaxy taken using the ESO Wide Field Imager we have identified so far 74 candidate RR Lyrae's in two CCD's hosting the main body of the galaxy.
