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
The Chemical Evolution of the Globular Cluster ω Centauri (NGC 5139)
We present abundances for 22 chemical elements in 10 red giant members of the massive Galactic globular cluster ω Centauri. The spectra are of relatively high spectral resolution and signal-to-noise.Expand
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
Evolution, Nucleosynthesis, and Yields of Low-mass Asymptotic Giant Branch Stars at Different Metallicities. II. The FRUITY Database
By using updated stellar low-mass stars models, we systematically investigate the nucleosynthesis processes occurring in asymptotic giant branch (AGB) stars. In this paper, we present a databaseExpand
Metallicities, Relative Ages, and Kinematics of Stellar Populations in ω Centauri*
We present results of an extensive spectroscopic survey of subgiant stars in the stellar system ω Cen. Using infrared Ca II triplet lines, we derived metallicities and radial velocities for more thanExpand
EVOLUTION, NUCLEOSYNTHESIS, AND YIELDS OF LOW-MASS ASYMPTOTIC GIANT BRANCH STARS AT DIFFERENT METALLICITIES
The envelope of thermally pulsing asymptotic giant branch (TP-AGB) stars undergoing periodic third dredge-up (TDU) episodes is enriched in both light and heavy elements, the ashes of a complexExpand
Galactic Chemical Evolution of Heavy Elements: From Barium to Europium
We follow the chemical evolution of the Galaxy for elements from Ba to Eu, using an evolutionary model suitable for reproducing a large set of Galactic (local and nonlocal) and extragalacticExpand
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
