Metal abundance of the eclipsing binary YZ Cas: discrepancy between atmospheric determinations for the Am component
E. Lastennet, D. Valls-Gabaud, C. Jordi
We review current and new estimates of the eclipsing binary YZ Cassiopeiae metallicity (Z). Since the individual components cover a quite large range of mass (1.35-2.31 Solar masse…

Stringent constraints on single-star evolution theory from masses and radii of well-detached binaries in star clusters
E. Lastennet, D. Valls-Gabaud, E. Oblak
Which sample of objects can give strong constraints on single-star evolution theory ? Whilst star cluster members share the same age and the same metallicity, many questions (e.g.…

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…
