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…
The age of the Milky Way inner stellar spheroid from RR Lyrae population synthesis
A. Savino, A. Koch, Z. Prudil +2
The central kiloparsecs of the Milky Way are known to host an old, spheroidal stellar population, whose spatial and kinematical properties set it apart from the boxy/peanut structu…
On the Metamorphosis of the Bailey diagram for RR Lyrae stars
G. Bono, V. F. Braga, J. Crestani +37
We collected over 6000 high-resolution spectra of four dozen field RR Lyrae (RRL) variables pulsating either in the fundamental (39 RRab) or in the first overtone (9 RRc) mode. We…
Humps and bumps: The effects of shocks on the optical light curves of fundamental-mode RR Lyrae stars
Z. Prudil, I. Dékány, R. Smolec +3
We present the most extended and homogeneous study carried out so far of the main and early shocks in 1485 RR~Lyrae stars in the Galactic bulge observed by the Optical Gravitationa…
Evidence for Galactic disc RR~Lyrae stars in the Solar neighbourhood
Z. Prudil, I. Dékány, E. K. Grebel +1
We present a kinematical study of 314 RR~Lyrae stars in the solar neighbourhood using the publicly available photometric, spectroscopic, and {\it Gaia} DR2 astrometric data to expl…
Blazhko effect in the Galactic bulge fundamental mode RR Lyrae stars II: Modulation shapes, amplitudes and periods
M. Skarka, Z. Prudil, J. Jurcsik
The number of stars observed by the Optical Gravitational Lensing Experiment (OGLE) project in the Galactic bulge offers an invaluable chance to study RR Lyrae stars in a statistic…
