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…
Starbursts in Barred Spiral Galaxies. II. Molecular and Optical Study of Three Wolf-Rayet Galaxies
T. Contini, H. Wozniak, S. Considere +1
We have searched for dense molecular gas in three barred spiral galaxies with young starbursts, NGC 3049, 5430 and 6764, which are known Wolf-Rayet galaxies. We detected HCN in the…
A Correlation Between CO Linewidth and Starburst Age in Barred Spiral Galaxies
T. Contini, H. Wozniak, S. Considere +1
New CO(1-0) and CO(2-1) profiles complemented by data from the literature are used to obtain CO linewidths for 29 barred spiral galaxies with young nuclear starbursts. The ages of…
