On the Use of Field RR Lyrae as Galactic Probes. V. Optical and radial velocity curve templates
V. F. Braga, J. Crestani, M. Fabrizio +29
We collected the largest spectroscopic catalog of RR Lyrae (RRLs) including 20,000 high-, medium- and low-resolution spectra for 10,000 RRLs. We provide the analy…
On the use of field RR Lyrae as Galactic probes: IV. New insights into and around the Oosterhoff dichotomy
M. Fabrizio, V. F. Braga, J. Crestani +30
We discuss the largest and most homogeneous spectroscopic dataset of field RR Lyrae variables (RRLs) available to date. We estimated abundances using both high-resolution and low-r…
Metallicities from high resolution spectra of 49 RR Lyrae Variables
Christina K. Gilligan, Brian Chaboyer, Massimo Marengo +12
Accurate metallicities of RR Lyrae are extremely important in constraining period-luminosity-metallicity relationships (PLZ), particularly in the near-infrared. We analyse 69 high-…
Metallicity of Galactic RR Lyrae from Optical and Infrared Light Curves: I. Period-Fourier-Metallicity Relations for Fundamental Mode RR Lyrae
Joseph P. Mullen, Massimo Marengo, Clara E. Martínez-Vázquez +12
We present newly-calibrated period--[Fe/H] relations for fundamental mode RR Lyrae stars in the optical and, for the first time, mid-infrared. This work's calibration datas…
The Carnegie Chicago Hubble Program X: Tip of the Red Giant Branch Distances to NGC 5643 and NGC 1404
Taylor J. Hoyt, Rachael L. Beaton, Wendy L. Freedman +7
The primary goal of the Carnegie Chicago Hubble Program (CCHP) is to calibrate the zero-point of the Type Ia supernova (SN Ia) Hubble Diagram through the use of Population II stand…
On the Use of Field RR Lyrae as Galactic Probes. II. A new S calibration to estimate their metallicity
J. Crestani, M. Fabrizio, V. F. Braga +33
We performed the largest and most homogeneous spectroscopic survey of field RR Lyraes (RRLs). We secured 6,300 high resolution (HR, R35,000) spectra for 143 RRLs (11…
