A possible new RR Lyrae variable star
Publications of the Astronomical Society of the Pacific, 1984UBV observations and a light curve are presented for a new variable star, chosen to be a companion star for the very hot degenerate dwarf PG 1520 + 525, and these data are found to be consistent with the interpretation that the new variable is a halo RR Lyrae variable of Bailey's type 'c'.

Three-dimensional motion of dwarf stars and RR Lyrae variables
Publications of the Astronomical Society of the Pacific, 1979A collection of 220 high-velocity dwarfs, 532 low-velocity dwarfs, and 114 RR Lyrae variables is given in tables with calculations of kinematical quantities in a three-dimensional model of galactic space. A metal indicator, Delta-S, for RR Lyrae variables is transformed into the ultraviolet excess, delta (0.6), which is utilized for a statistical study

Applied Machine Learning for and Analysis of RR Lyrae Variable Stars
2018 2nd International Conference on I-SMAC (IoT in Social, Mobile, Analytics and Cloud) (I-SMAC)I-SMAC (IoT in Social, Mobile, Analytics and Cloud) (I-SMAC), 2018 2nd International Conference on, 2018Machine Learning is being used extensively in various fields. From health, physical systems and astronomy, the scope of automating process and analyzing data has no limits, added by the sheer amount of computation prowess. In this paper, we will use various Machine Learning Algorithms to perform supervised classification of one of the most relevant and

Radial and Nonradial Beating Modes for RR Lyrae Variable Star Blazhko Effect
AIP Conference Proceedings, 2009At the eleventh conference in the Los Alamos pulsation series in 1992, this author suggested that the observed fundamental mode period of the variable star RR Lyrae can beat with the nonradial l = 1, g4 mode to produce the observed Blazhko effect seen in that star.

High-Cadence Stellar Variability Studies of Galactic RR Lyrae Stars with DECam
2023As part of the DECam Alliance for Transients (DECAT), a consortium of time- domain DECam programs, the DECam Deep Drilling Program (DDP) is being conducted at the Blanco 4m telescope, located at Cerro Tololo Inter-American Observatory, Chile. The DDP includes the DECaPS East field, situated in the Galactic bulge at coordinates (RA, DEC)(J2000) = (18:03:
