On the Use of Field RR Lyrae as Galactic Probes -- VIII. Early Formation of the Galactic Spheroid

G. Bono, V. F. Braga, M. Fabrizio +54

We introduce a new photometric catalog of RR Lyrae variables (RRLs, 300,000) mainly based on data available in public datasets. We also present the largest and most homogeneo…

The dwarf irregular galaxy NGC 6822. II. Young, intermediate and old stellar populations: comparison between theory and observations

Maria Tantalo, Giuseppe Bono, Maurizio Salaris +14

This paper presents a quantitative analysis of the stellar content in the Local Group dwarf irregular galaxy NGC 6822 by comparing stellar evolution models and observations in colo…

Oxygen, sulfur, and iron radial abundance gradients of classical Cepheids across the Galactic thin disk

R. da Silva, V. D'Orazi, M. Palla +25

Classical Cepheids (CCs) are solid distance indicators and tracers of young stellar populations. Our aim is to provide iron, oxygen, and sulfur abundances for the largest and most…

On the dwarf irregular galaxy NGC 6822. I. Young, intermediate and old stellar populations

Maria Tantalo, Massimo Dall'Ora, Giuseppe Bono +13

We present accurate and deep multi-band () photometry of the Local Group dwarf irregular galaxy NGC 6822. The images were collected with wide field cameras at 2m/4m- (INT,CT…

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…
