Analysis of RGU Photometry in Selected Area 51
S. Bilir, S. Karaali, R. Buser
A low-latitude anticenter field (l=189, b=+21) is investigated by using the full calibration tools of RGU photometry. The observed RGU data are reduced to the standard system and t…
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…
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…
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…
