The MAGIC project. III. Radial and azimuthal Galactic abundance gradients using classical Cepheids
V. Kovtyukh, B. Lemasle, G. Bono +7
Radial abundance gradients provide sound constraints for chemo-dynamical models of galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their chem…
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…
A revisited study of Cepheids in open clusters in the Gaia era
Gustavo E. Medina, Bertrand Lemasle, Eva K. Grebel
In this paper we revisit the problem of identifying bona fide cluster Cepheids by performing an all-sky search for Cepheids associated with open clusters and making use of state-of…
Milky Way archaeology using RR Lyrae and type II Cepheids I. The Orphan stream in 7D using RR Lyrae stars
Z. Prudil, M. Hanke, B. Lemasle +19
We present a chemo-dynamical study of the Orphan stellar stream using a catalog of RR~Lyrae pulsating variable stars for which photometric, astrometric, and spectroscopic data are…
