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…
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…
Simultaneous (age, metallicity) estimates of the Hyades open cluster from three binary systems
E. Lastennet, D. Valls-Gabaud, T. Lejeune +1
Three binary systems in the Hyades open cluster, with known metallicity and good Johnson photometric data are used to test the validity of three independent sets of stellar evoluti…
Consequences of Hipparcos parallaxes for stellar evolutionary models. Three Hyades binaries: V818 Tauri, 51 Tauri, and Tauri
E. Lastennet, D. Valls-Gabaud, T. Lejeune +1
Three binary systems in the Hyades open cluster (51 Tau, V818 Tau, and Tau}, with known metallicity and good Johnson photometric data are used to test the validity of three i…
