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…
Initial mass function effects on the colour evolution of disk galaxies
P. Westera, M. Samland, S. J. Kautsch +2
In this work, we want to find out if the IMF can be determined from colour images, integrated colours, or mass-to-light ratios, especially at high redshift, where galaxies cannot b…
A standard stellar library for evolutionary synthesis: I. Calibration of theoretical spectra
T. Lejeune, F. Cuisinier, R. Buser
A comprehensive hybrid library of synthetic stellar spectra based on three original grids of model atmosphere spectra by Kurucz (1995), Fluks et al. (1994), and Bessell et al. (198…
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…
Model atmosphere calibration for synthetic photometry applications: the uvby Stromgren photometric system
T. Lejeune, E. Lastennet, P. Westera +1
In view of the importance of accurate fundamental stellar parameters for `Spectro-photometric dating of stars and galaxies", we present simultaneous effective temperature and metal…
Modeling age and metallicity in globular clusters: a comparison of theoretical giant branch isochrones
T. Lejeune, R. Buser
In view of the important contributions of red giants to the integrated light in evolutionary synthesis calculations of old stellar populations in clusters and galaxies, we provide…
