Atmospheric parameters for non-interacting eclipsing binaries: preliminary results from synthetic photometry
E. Lastennet, F. Cuisinier, T. Lejeune
Double-lined spectroscopic binaries which are also eclipsing provide the most accurate stellar data, and are consequently of first importance to improve stellar evolution modelling…
Temperature predictions for dust embedded AGB stars: how far can we go with synthetic near-infrared photometry ?
E. Lastennet, S. Lorenz-Martins, F. Cuisinier +1
We discuss the possibilities of the BaSeL models in its lowest temperature boundary (Teff ~ 2500 K for cool giants) to provide the Teff of AGB stars. We present the first step of o…
Preparation of the COROT space mission: fundamental stellar parameters determinations from photometric and spectroscopic analyses for COROT potential target candidates
E. Lastennet, F. Lignieres, R. Buser +4
We present a sample of 9 nearby F-type stars with detailed spectroscopic analyses to investigate the Basel Stellar Library (BaSeL) in two photometric systems simultaneously, UBV Jo…
The Galactic Bulge: The Stellar and Planetary Nebulae Populations
F. Cuisinier, J. Koppen, A. Acker +1
We compare abundances patterns in the Bulge for elements observed in stars and in planetary nebulae. Some alpha elements, like Mg and Ti, are overabundant respect to Fe, and others…
Stars and Planetary Nebulae in the Galactic Bulge
F. Cuisinier, J. Koppen, A. Acker +1
We compare the populations of Red Giant stars and Planetary Nebulae in the Galactic Bulge, in the light of recent determinations of their abundances patterns. We find both populati…
Exploration of the BaSeL stellar library for 9 F-type stars COROT potential targets
E. Lastennet, F. Lignieres, R. Buser +4
The Basel Stellar Library (BaSeL models) is constituted of the merging of various synthetic stellar spectra libraries, with the purpose of giving the most comprehensive coverage of…
