The chemical composition of the Herbig Ae SB2 system AK Sco (HD152404)
F. Castelli, S. Hubrig, S. P. Jarvinen +1
We investigate the stellar atmospheres of the two components of the Herbig Ae SB2 system AK Sco to determine the elements present in the stars and their abundance. Equal stellar pa…
Magnetic fields of Herbig Ae/Be stars
S. Hubrig, I. Ilyin, M. Schoeller +5
We report on the status of our spectropolarimetric studies of Herbig Ae/Be stars carried out during the last years. The magnetic field geometries of these stars, investigated with…
A large stellar evolution database for population synthesis studies. II. Stellar models and isochrones for an alpha-enhanced metal distribution
A. Pietrinferni, S. Cassisi, M. Salaris +1
[Abridged] We present a large, new set of stellar evolution models and isochrones for an alpha-enhanced metal distribution typical of Galactic halo and bulge stars; it represents a…
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…
