CS 30322-023: an ultra metal-poor TP-AGB star?
T. Masseron, S. Van Eck, B. Famaey +6
With [Fe/H] = -3.5, CS 30322-023 is the most metal-poor star to exhibit a clear s-process signature and the most metal-poor ``lead star'' known. CS 30322-023 is also remarkable in…
A VLT-UVES spectrscopic analysis of C-rich Fe-poor stars
T. Masseron, B. Plez, F. Primas +2
Large surveys of very metal-poor stars have revealed in recent years that a large fraction of these objects were carbon-rich, analogous to the more metal-rich CH-stars. The abundan…
Cosmic abundances: The impact of stellar duplicity
A. Jorissen, S. Van Eck
The mass-transfer scenario links chemical peculiarities with stellar duplicity for an increasing number of stellar classes (classical and dwarf barium stars, subgiant and giant CH…
The HIPPARCOS Hertzsprung-Russell diagram of S stars: Probing nucleosynthesis and dredge-up
S. Van Eck, A. Jorissen, S. Udry +2
HIPPARCOS trigonometrical parallaxes make it possible to compare the location of Tc-rich and Tc-poor S stars in the Hertzsprung-Russell (HR) diagram: Tc-rich S stars are found to b…
