Abstract

For the past two years we have been using the FORS multi-object spectrograph at the VLT to investigate the blue supergiant populations in nearby spiral galaxies. For the first time we have obtained quantitative spectroscopy to a distance up to 7 Mpc, estimating abundances and wind properties of luminous A-type supergiants. We have begun to test the wind momentum-luminosity relationship as an extragalactic distance indicator beyond the Local Group. Our very preliminary results on single blue supergiants in NGC 3621 and NGC 300 make us look with optimism at the future of the project, especially when looking ahead to the new generation of multi-object spectrographs which will be soon made available at 8 meter-class telescopes.
