Magnetic fields in Herbig Ae stars
S. Hubrig, M. Schoeller, R. V. Yudin
Herbig Ae stars are young A-type stars in the pre-main sequence evolutionary phase with masses of ~1.5-3 M_o. They show rather intense surface activity (Dunkin et al. 1997) and inf…

Color transformations and bolometric corrections for Galactic halo stars: alpha-enhanced vs scaled-solar results
Santi Cassisi, Maurizio Salaris, Fiorella Castelli +1
We have performed the first extensive analysis of the impact of an [alpha/Fe]>0 metal distribution on broadband colors in the parameter space (surface gravity, effective temperatur…

A large stellar evolution database for population synthesis studies. I. Scaled solar models and isochrones
A. Pietrinferni, S. Cassisi, M. Salaris +1
We present 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…
