A Bayesian Approach to Calibrating Period-Luminosity Relations of RR Lyrae Stars in the Mid-Infrared
statistical methods RR Lyrae distance scale
2012/2/23
A Bayesian approach to calibrating period-luminosity (PL) relations has substantial benefits over generic least-squares fits. In particular, the Bayesian approach takes into account the full prior dis...
The Optical Gravitational Lensing Experiment. Analysis of the bulge RR Lyrae population from the OGLE-III data
Optical Gravitational Lensing Experiment Analysis bulge population
2011/10/10
We have analyzed data on 16,838 RR Lyrae variables observed toward the Galactic bulge during the third phase of the Optical Gravitational Lensing Experiment (OGLE) in 2001-2009. Using this type of sta...
The Kepler Mission is a Discovery mission supported by NASA's Science Mission Directorate, and its primary aim is to discover Earth-sized planets in the habitable zone of solar-type stars. The space t...
Period Change Similarities among the RR Lyrae Variables in Oosterhoff I and Oosterhoff II Globular Systems
Period Change Similarities among RR Lyrae Variables
2011/1/11
We present period change rates (dP/dt) for 42 RR Lyrae variables in the globular cluster IC$\,$4499. Despite clear evidence of these period increases or decreases, the observed period change rates are...

New Double-Mode Other RR Lyrae Stars from WASP Data
2010/11/11
The data from the first public data release of the exoplanet transit survey WASP (Wide Angle Search for Planets; Butters et al., 2010) were studied for a number of known and suspected RR Lyrae stars (...
Long-term photometric monitoring of Messier 5 variables: I. Period changes of RR Lyrae stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
The period changes of 86 M5 RR Lyrae stars have been investigated on a one-hundred-year time base. The published observations have been supplemented by archival Asiago, Konkoly and Las Campanas photog...
