AGB nucleosynthesis in the Large Magellanic Cloud. Detailed abundance analysis of the RV Tauri star MACHO47.2496.8
M. Reyniers, C. Abia, H. Van Winckel +4
Context. Abundance analysis of post-AGB objects as probes of AGB nucleosynthesis. Aims. A detailed photospheric abundance study is performed on the carbon-rich post-AGB candidate M…
High resolution optical spectroscopy of IRAS 09425-6040 (=GLMP 260)
D. A. Garcia-Hernandez, C. Abia, A. Manchado +1
We present high resolution optical spectroscopic observations of IRAS 09425-6040, a peculiar, extremely red, C-rich AGB star showing prominent O-rich dust features in its ISO infra…
Chemical analysis of carbon stars in the Local Group: I. The Small Magellanic Cloud and the Sagittarius dwarf spheroidal galaxy
P. De Laverny, C. Abia, I. Dominguez +5
We present the first results of our ongoing chemical study of carbon stars in the Local Group of galaxies. We used spectra obtained with UVES at the 8.2 m Kueyen-VLT telescope and…
First detection of a lithium rich carbon star in the Draco dwarf galaxy: evidence for a young stellar population
I. Dominguez, C. Abia, O. Straniero +2
We present a spectroscopic study of D461, a giant star belonging to Draco dwarf spheroidal galaxy. From spectral synthesis in LTE we derive a lithium abundance of log e(Li)=3.5+/-0…
The Chemical Composition of Carbon C(N) stars
C. Abia, I. Dominguez, R. Gallino +5
A chemical study of normal Galactic C(N) carbon stars is presented. Abundances of Li, CNO isotopes and s-elements are derived. The derived abundances of s-elements nicely agree wit…
Lithium abundances in the atmospheres of SLR C--giants WZ Cas and WX Cyg from resonance and subordinate Li I lines
Larisa A. Yakovina, Yakiv V. Pavlenko, Carlos Abia
Lithium abundances in the atmospheres of the super Li-rich C-giants WZ Cas and WX Cyg are derived by the spectral synthesis technique {\bf using} the Li I resonance line at λ670.8…
