O stars with weak winds: the Galactic case
Fabrice Martins, Daniel Schaerer, John Hillier +3
We study the stellar and wind properties of a sample of Galactic O dwarfs to track the conditions under which weak winds (i.e mass loss rates lower than ~ 1e-8 Msol/yr) appear. The…
Stellar populations and Lya emission in two lensed z>~6 galaxies
Daniel Schaerer, Roser Pello
We present an analysis of two strongly lensed galaxies at z=6.56 and z ~ 7 for which multi-band photometric and spectroscopic observations are available. For one source the data in…
A VLT study of metal-rich extragalactic H II regions. I. Observations and empirical abundances
Fabio Bresolin, Daniel Schaerer, Rosa Gonzalez Delgado +1
We have obtained spectroscopic observations from 3600 Angstrom to 9200 Angstrom with FORS at the Very Large Telescope for approximately 70 H II regions located in the spiral galaxi…
A new calibration of stellar parameters of Galactic O stars
F. Martins, D. Schaerer, D. J. Hillier
We present new calibrations of stellar parameters of O stars at solar metallicity taking non-LTE, wind, and line-blanketing effects into account. Gravities and absolute visual magn…
