RR Lyrae variables in Galactic Globular Clusters: distribution of periods and synthetic models

M. Castellani, V. Castellani, S. Cassisi +1

We present some applications of our Synthetic Horizontal Branches (SHB) simulations, aimed to reproduce the peculiar period distributions of RR Lyrae belonging to the Galactic Glob…

The lithium content of the globular cluster NGC 6397

P. Bonifacio, L. Pasquini, F. Spite +16

We make use of high resolution, high signal-to-noise ratio spectra of 12 turn-off stars in the metal-poor globular cluster NGC 6397 to measure its lithium content. We conclude that…

On the observational properties of He-burning stars: some clues on the tilt of the HB in metal rich clusters

G. Raimondo, V. Castellani, S. Cassisi +2

We investigate the predicted Color-Magnitude distribution of metal-rich Horizontal Branch (HB) stars, discussing selected theoretical models computed under various assumptions abou…

The field of NGC 6397 as a test for Galactic models

V. Castellani, S. Degl'Innocenti, S. Petroni +1

Taking advantage of recent HST data for field stars in the region of the Galactic globular cluster NGC 6397, we tested the predictions of several Galactic models with star counts r…

Asymptotic Giant Branch predictions: theoretical uncertainties

S. Cassisi, V. Castellani, S. Degl'Innocenti +2

In this paper we investigate the level of agreement between observations and "new" Asymptotic Giant Branch (AGB) models, as produced by updating the physical inputs adopted in prev…

Theoretical insights into the RR Lyrae K-band Period-Luminosity relation

G. Bono, F. Caputo, V. Castellani +1

Based on updated nonlinear, convective pulsation models computed for several values of stellar mass, luminosity and metallicity, theoretical constraints on the K-band Period-Lumino…
