On the Impact of Helium Content on the RR Lyrae Distance Scale
M. Marconi, G. Bono, A. Pietrinferni +3
We constructed new sets of He-enhanced (Y = 0.30, Y = 0.40) nonlinear, time-dependent convective hydrodynamical models of RR Lyrae (RRL) stars covering a broad range in metal abund…
On the RR Lyrae stars in globulars: V. the complete Near-Infrared (JHKs) census of omega Centauri RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +35
We present a new complete Near-Infrared (NIR, ) census of RR Lyrae stars (RRLs) in the globular Cen (NGC 5139). We collected 15,472 images with 4-8m class telesc…
On the RR Lyrae stars in globulars: IV. Centauri Optical UBVRI Photometry
V. F. Braga, P. B. Stetson, G. Bono +31
New accurate and homogeneous optical UBVRI photometry has been obtained for variable stars in the Galactic globular Cen (NGC 5139). We secured 8202 CCD images covering a time i…
On a new theoretical framework for RR Lyrae stars I: the metallicity dependence
M. Marconi, G. Coppola, G. Bono +7
We present new nonlinear, time-dependent convective hydrodynamical models of RR Lyrae stars computed assuming a constant helium-to-metal enrichment ratio and a broad range in metal…
Search for a circum-planetary material and orbital period variations of short-period Kepler exoplanet candidates
Z. Garai, G. Zhou, J. Budaj +1
A unique short-period Mercury-size Kepler exoplanet candidate KIC012557548b has been discovered recently by Rappaport et al. (2012). This object is a transiting disintegrating exop…
The Kepler RR Lyrae SC Data Set: Period Variation and Blazhko Effect
Robert F. Stellingwerf, James M. Nemec, Pawel Moskalik
We study the 1.28 million short cadence {\it Kepler} data points (Q5-Q14) for RR Lyrae covering 24 cycles of the Blazhko variation, and more than one half of the 4-year modulation…
