Photometric properties of theoretical spectral libraries for GAIA photometry
T. Lejeune
Photometric properties of various spectral libraries of synthetic stellar spectra derived from the ATLAS 9 (Castelli et al. 1997), the PHOENIX NextGen (Hauschildt et al. 1999a, 199…
The BaSeL library as a basic tool to provide fundamental stellar parameters of future space missions: COROT and GAIA
E. Lastennet, T. Lejeune, F. Cuisinier
COROT and GAIA are two future major space missions directly connected to most of the stellar astrophysic questions, from stellar physics to evolution of galaxies. We describe a pro…
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…
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…
Influence of Hipparcos on Hyades age estimates from three binary systems
E. Lastennet, D. Valls-Gabaud, T. Lejeune +1
Three independent sets of stellar theoretical models are tested with well-detached systems of the Hyades open cluster: 51 Tau, V818 Tau, and Tau. The choice of these objects…
Metallicity calibration of theoretical stellar SEDs using UBVRIJHKL photometry of globular clusters
P. Westera, Th. Lejeune, R. Buser
Although stellar SED models are constantly improving and seem to show similar differential tendencies as measured spectra, their absolute properties (eg. absolute flux in different…
