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…
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…
Metallicity-dependent effective temperature determination for eclipsing binaries from synthetic uvby Stromgren photometry
E. Lastennet, T. Lejeune, P. Westera +1
Stromgren synthetic photometry from an empirically calibrated grid of stellar atmosphere models has been used to derive the effective temperature of each component of double lined…
