The Milky Way and the Tully-Fisher relation
Abstract
We present an updated estimate of the surface density and surface brightness in B,V,I of the local Galactic disc, based on a model for the "Solar cylinder" calibrated to reproduce Hipparcos and Tycho star counts. We discuss the mass-to-light ratio of the local stellar disc and infer the global luminosity of the Milky Way, which results underluminous with respect to the Tully-Fisher relation.
