A new and homogeneous metallicity scale for Galactic classical Cepheids II. The abundance of iron and alpha elements
R. da Silva, J. Crestani, G. Bono +18
Classical Cepheids are the most popular distance indicators and tracers of young stellar populations. The key advantage is that they are bright and they can be easily identified in…
A Very Metal-poor RR Lyrae Star with a Disk Orbit Found in the Solar Neighborhood
Noriyuki Matsunaga, Akinori Itane, Kohei Hattori +28
Metal-deficient stars are important tracers for understanding the early formation of the Galaxy. Recent large-scale surveys with both photometric and spectroscopic data have report…
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…
