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…
Accurate fundamental parameters for Lower Main Sequence Stars
L. Casagrande, L. Portinari, C. Flynn
We derive an empirical effective temperature and bolometric luminosity calibration for G and K dwarfs, by applying our own implementation of the InfraRed Flux Method to multi-band…
On the mass-to-light ratio of the local Galactic disc and the optical luminosity of the Galaxy
Chris Flynn, Johan Holmberg, Laura Portinari +2
We measure the volume luminosity density and surface luminosity density generated by the Galactic disc, using accurate data on the local luminosity function and the disc's vertical…
The Tully-Fisher relation and its evolution with redshift in cosmological simulations of disc galaxy formation
Laura Portinari, Jesper Sommer-Larsen
We present predictions on the evolution of the Tully-Fisher (TF) relation with redshift, based on cosmological N-body/hydrodynamical simulations of disc galaxy formation and evolut…
The colours of the Sun
Johan Holmberg, Chris Flynn, Laura Portinari
We compile a sample of Sun-like stars with accurate effective temperatures, metallicities and colours (from the UV to the near-IR). A crucial improvement is that the effective temp…
Simulating galaxy clusters -- I. Thermal and chemical properties of the intra-cluster medium
A. D. Romeo, J. Sommer-Larsen, L. Portinari +1
We have performed a series of N-body/hydrodynamical (TreeSPH) simulations of clusters and groups of galaxies, selected from cosmological N-body simulations within a CDM framewor…
