The RR Lyrae distance scale is reviewed. In particular, we discuss theoretical and empirical methods currently adopted in the literature. Moreover, we also outline pros and cons of optical and near-infrared mean magnitudes to overcome some of the problems currently affecting RR Lyrae distances. The importance of the K-band Period-Luminosity-Metallicity (PLZ K ) relation for RR Lyrae is also discussed, together with the absolute calibration of the zero-point. We also mention some preliminary… Expand
Near-Infrared Observations of RR Lyrae Variables in Galactic Globular Clusters. I. The Case of M92
We present near-infrared (NIR) J-, H-, and K-band time series observations of the Galactic globular cluster (GGC) M92. On the basis of these data, we derive well-sampled light curves for 11 out ofExpand
The distance to the LMC cluster Reticulum from the K-band Period-Luminosity-Metallicity relation of RR Lyrae stars
We present new and accurate Near-Infrared J and Ks-band data of the Large Magellanic Cloud cluster Reticulum. Data were collected with SOFI available at NTT and covering an area of approximately (5 xExpand
The Araucaria Project: The Distance to the Small Magellanic Cloud from Near-Infrared Photometry of RR Lyrae Variables
We have obtained deep infrared (IR) J- and K-band observations of five fields located in the Large Magellanic Cloud (LMC) bar with the ESO New Technology Telescope equipped with the SOFI IR camera.Expand
RR Lyrae variables in the Small Magellanic Cloud – I. The central region
We have performed the Fourier decomposition analysis of 11-yr V-band light curves of a carefully selected sample of 100 RR Lyrae variables, detected in the central regions of the Small MagellanicExpand
Distance determination from the Cepheid and RR Lyrae period-luminosity relations
Abstract Cepheids and RR Lyrae stars are important pulsating variable stars in distance scale work because they serve as standard candles. Cepheids follow well-defined period-luminosity (PL)Expand
Distance to Galactic globulars using the near‐infrared magnitudes of RR Lyrae stars – IV. The case of M5 (NGC 5904)
We present new and accurate near-infrared (NIR) J, K-band time series data for the Galactic globular cluster (GC) M5 = NGC 5904. Data were collected with SOFI at the NTT (71 J+ 120 K images) and withExpand
Old-Aged Primary Distance Indicators
TLDR
A comprehensive review for three primary standard candles from Population II: (i) RR Lyrae type variables (RRL), (ii) type II Cepheid variables (T2C), and (iii) the tip of the red giant branch (TRGB) is presented. Expand
CCD PHOTOMETRY OF CANDIDATE RR LYRAE STARS IN THE SLOAN DIGITAL SKY SURVEY
We present unfiltered CCD photometry of a sample of 71 candidate RR Lyrae stars during 2003 and 2004, out of 148 candidate stars that were selected from Sloan Digital Sky Survey (SDSS) commissioningExpand
Synthetic properties of bright metal-poor variables I. "Anomalous" Cepheids
We present new grids of evolutionary models for the so-called "Anomalous" Cepheids (ACs), adopting Z = 0.0001 and various assumptions on the progenitor mass and mass-loss efficiency. TheseExpand
