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…

New Near-Infrared light-curve templates for RR Lyrae variables

V. F. Braga, P. B. Stetson, G. Bono +34

We provide homogeneous optical (UBVRI) and near-infrared (JHK) time series photometry for 254 cluster (omega Cen, M4) and field RR Lyrae (RRL) variables. We ended up with more than…

On a new and homogeneous metallicity scale for Galactic classical Cepheids - I. Physical parameters

B. Proxauf, R. da Silva, V. V. Kovtyukh +23

We gathered more than 1130 high-resolution optical spectra for more than 250 Galactic classical Cepheids. The spectra were collected with different optical spectrographs: UVES at V…

On the chemical abundances of Miras in clusters: V1 in the metal-rich globular NGC 5927

V. D'Orazi, D. Magurno, G. Bono +50

We present the first spectroscopic abundance determination of iron, alpha-elements (Si, Ca and Ti) and sodium for the Mira variable V1 in the metal-rich globular cluster NGC 5927.…

On the RR Lyrae stars in globulars: V. the complete Near-Infrared (JHKs) census of omega Centauri RR Lyrae variables

V. F. Braga, P. B. Stetson, G. Bono +35

We present a new complete Near-Infrared (NIR, ) census of RR Lyrae stars (RRLs) in the globular Cen (NGC 5139). We collected 15,472 images with 4-8m class telesc…
