On the effect of helium enhancement on bolometric corrections and Teff-colour relations
L. Girardi, F. Castelli, G. Bertelli +1
We evaluate the effects that variations in He content have on bolometric corrections and Teff-colour relations. To this aim, we compute ATLAS9 model atmospheres and spectral energy…

The Helium abundance and Delta Y / Delta Z in Lower Main Sequence stars
Luca Casagrande, Chris Flynn, Laura Portinari +2
We use nearby K dwarf stars to measure the helium-to-metal enrichment ratio, a diagnostic of the chemical history of the Solar Neighbourhood. Our sample of K dwarfs has homogeneous…

Towards simulating the photometry, chemistry, mass loss and pulsational properties of AGB star populations in resolved galaxies
Leo Girardi, Paola Marigo
Extended and updated grids of TP-AGB tracks have been implemented in the TRILEGAL population synthesis code, which generates mock stellar catalogues for a galaxy given its mass, di…
