A large stellar evolution database for population synthesis studies. i. scaled solar models and isochrones
Adriano Pietrinferni,Adriano Pietrinferni,Santi Cassisi,Santi Cassisi,Maurizio Salaris,Fiorella Castelli +5 more
TL;DR: A large and updated stellar evolution database for low-, intermediate-, and high-mass stars in a wide metallicity range, suitable for studying Galactic and extragalactic simple and composite stellar populations using population synthesis techniques is presented in this paper.

A large stellar evolution database for population synthesis studies. I. Scaled solar models and isochrones
TL;DR: In this paper, a large and updated stellar evolution database for low-, intermediate-and high-mass stars in a wide metallicity range is presented, suitable for studying Galactic and extragalactic simple and composite stellar populations using population synthesis techniques.
Journal ArticleDOI
A triple main sequence in the globular cluster NGC 2808
Giampaolo Piotto,Luigi R. Bedin,Joseph M. Anderson,Ivan R. King,Santi Cassisi,Antonino Milone,S. Villanova,Adriano Pietrinferni,Alvio Renzini +8 more
TL;DR: In this paper, the main sequence (MS) of the globular cluster NGC 2808 splits into three separate branches, and the three branches may be associated with the complexities of the cluster's horizontal branch and of its abundance distribution.
Journal ArticleDOI
A large stellar evolution database for population synthesis studies. II. Stellar models and isochrones for an alpha-enhanced metal distribution
TL;DR: In this article, Pietrinferni et al. presented a set of stellar evolution models and isochrones for an alpha-enhanced metal distribution typical of Galactic halo and bulge stars.
Journal ArticleDOI
Metallicities on the double main sequence of ω centauri imply large helium enhancement
Giampaolo Piotto,S. Villanova,Luigi R. Bedin,Luigi R. Bedin,Raffaele Gratton,Santi Cassisi,Yazan Momany,Alejandra Recio-Blanco,Sara Lucatello,Jay Anderson,Ivan R. King,Adriano Pietrinferni,Giovanni Carraro +12 more
TL;DR: In this article, spectroscopic results showed that the blue main sequence is less metal-poor than the red main sequence, and they used stellar structure models to show that only greatly enhanced helium can explain the color difference between the two main sequences.
