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…
128Xe and 130Xe: Testing He-shell burning in AGB stars
R. Reifarth, F. Kaeppeler, F. Voss +4
The s-process branching at 128I has been investigated on the basis of new, precise experimental (n,g) cross sections for the s-only isotopes 128Xe and 130Xe. This branching is uniq…
The bottleneck of the CNO burning and the age of the Globular Clusters
G. Imbriani, H. Costantini, A. Formicola +27
The transition between the Main Sequence and the Red Giant Branch in low mass stars is powered by the onset of the CNO burning, whose bottleneck is the N(p,O. The L…
Discovery of an anomalous Sub Giant Branch in the Color Magnitude Diagram of omega Centauri
F. R. Ferraro, A. Sollima, E. Pancino +4
Using deep high-resolution multi-band images taken with the Very Large Telescope and the Hubble Space Telescope, we discovered a new anomalous sequence in the Color Magnitude Diagr…
