Comprehensive study of five candidate delta Scuti-type pulsators in detached eclipsing binaries

T. Pawar, K. G. Hełminiak, A. Moharana +4

Pulsating stars in eclipsing binaries (EBs) provide an excellent opportunity to obtain precise, model-independent stellar parameters for studying oscillations in detail. One common…

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…

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…

A Plague of Magnetic Spots Among the Hot Stars of Globular Clusters

Yazan Al Momany, Simone Zaggia, Marco Montalto +15

Six decades and counting, the formation of hot ~20,000-30,000 K Extreme Horizontal Branch (EHB) stars in Galactic Globular Clusters remains one of the most elusive quests in stella…
