The alpha -enhanced Isochrones and Their Impact on the FITS to the Galactic Globular Cluster System
We analyze in detail the effect produced by the enhancement of the α-elements O, Ne, Mg, Si, S, and Ca on the evolutionary properties of low-mass, low-metallicity stars. In particular we address theExpand

THE GIANT, HORIZONTAL, AND ASYMPTOTIC BRANCHES OF GALACTIC GLOBULAR CLUSTERS. I. THE CATALOG, PHOTOMETRIC OBSERVABLES, AND FEATURES
A catalog including a set of the most recent color-magnitude diagrams (CMDs) is presented for a sample of 61 Galactic globular clusters (GGCs). We used this database to perform a homogeneousExpand

Explosive Yields of Massive Stars from Z = 0 to Z = Z?
We present a new and homogeneous set of explosive yields for masses 13, 15, 20, 25, 30, and 35 M? and metallicities Z = 0, 10-6, 10-4, 10-3, 6 ? 10-3, and 2 ? 10-2. A wide network extending up to MoExpand

The Nucleosynthesis of 26Al and 60Fe in Solar Metallicity Stars Extending in Mass from 11 to 120 M☉: The Hydrostatic and Explosive Contributions
We present the 26Al and 60Fe yields produced by a generation of solar metallicity stars ranging in mass between 11 and 120 M☉. We discuss the production sites of these γ-ray emitters and quantify theExpand

EVOLUTION AND NUCLEOSYNTHESIS IN LOW-MASS ASYMPTOTIC GIANT BRANCH STARS. II. NEUTRON CAPTURE AND THE s-PROCESS
We present a new analysis of neutron capture occurring in low-mass asymptotic giant branch (AGB) stars suffering recurrent thermal pulses. We use dedicated evolutionary models for stars of initialExpand

The O-Na and Mg-Al anticorrelations in turn-off and early subgiants in globular clusters
High dispersion spectra (R > 40 000) for a quite large number of stars at the main sequence turn-o and at the base of the giant branch in NGC 6397 and NGC 6752 were obtained with the UVES on KueyenExpand

Intermediate-Mass Stars: Updated Models
A new set of stellar models in the mass range 1.2-9 M☉ is presented. The adopted chemical compositions cover the typical Galactic values, namely, 0.0001 ≤ Z ≤ 0.02 and 0.23 ≤ Y ≤ 0.28. A comparisonExpand

TOPoS - II. On the bimodality of carbon abundance in CEMP stars Implications on the early chemical evolution of galaxies
Context. In the course of the TOPoS (Turn Off Primordial Stars) survey, aimed at discovering the lowest metallicity stars, we have found several carbon-enhanced metal-poor (CEMP) stars. These starsExpand

Evolution and Nucleosynthesis in Low-Mass Asymptotic Giant Branch Stars. I. Formation of Population I Carbon Stars
New models of thermally pulsing asymptotic giant branch (TP-AGB) stars of low mass and solar chemical composition are presented, namely, 1 ≤ M/M☉ ≤ 3, Z = 0.02, and Y = 0.28. The influence of variousExpand
