Near-Infrared Observations of RR Lyrae Variables in Centauri
M. Del Principe, A. M. Piersimoni, J. Storm +6
We present Near-Infrared (NIR) and -band observations for 181 RR Lyrae stars in the Galactic Globular Cluster Cen. The comparison between predicted and empirical slope…
Stellar evolutionary models: uncertainties and systematics
S. Cassisi
In this last decade, our knowledge of evolutionary and structural properties of stars of different mass and chemical composition is significantly improved. This result has been ach…
The double main sequence of Omega Centauri
L. R. Bedin, G. Piotto, J. Anderson +4
Recent, high precision photometry of Omega Centauri, the biggest Galactic globular cluster, has been obtained with Hubble Space Telescope. The color magnitude diagram reveals an un…
Models for extremely metal-poor halo stars
A. Weiss, H. Schlattl, M. Salaris +2
Two alternative scenarios concerning the origin and evolution of extremely metal-poor halo stars are investigated. The first one assumes that the stars have been completely metal-f…
The evolutionary properties of intermediate-mass stars
S. Cassisi
We briefly review the main problems related to the computation of the evolution of intermediate-mass stars: the treatment of turbulent convection and the occurrence of blue loops d…
HST multiband photometry of the globular cluster NGC 6388
G. Busso, G. Piotto, S. Cassisi
We present color-magnitude diagrams (CMD) of the globular cluster NGC 6388 based on HST multiband photometry (F255W, F336W, F439W, F555W). In this paper we focus our attention on t…
