A large C+N+O abundance spread in giant stars of the globular cluster NGC 1851
David Yong, Frank Grundahl, Francesca D'Antona +3
Abundances of C, N, and O are determined in four bright red giants that span the known abundance range for light (Na and Al) and s-process (Zr and La) elements in the globular clus…
A Small Step on the Long Road to Understanding the R-Stars: CNO Cycling in Candidate R-Star Progenitors
George Angelou, John Lattanzio
Recent work has proposed that a merger event between a red-giant and a He white dwarf may be responsible for the production of R-stars (Izzard et al, 2007). We investigate the prop…
Fluorine in carbon-enhanced metal-poor stars: a binary scenario
M. Lugaro, S. E. de Mink, R. G. Izzard +8
A super-solar fluorine abundance was observed in the carbon-enhanced metal-poor (CEMP) star HE 1305+0132 ([F/Fe] = +2.90, [Fe/H] = -2.5). We propose that this observation can be ex…
Abundances in intermediate-mass AGB stars undergoing third dredge-up and hot-bottom burning
J. A. McSaveney, P. R. Wood, M. Scholz +2
High dispersion near-infrared spectra have been taken of seven highly-evolved, variable, intermediate-mass (4-6 Msun) AGB stars in the LMC and SMC in order to look for C, N and O v…
Deep Mixing of He-3: Reconciling Big Bang and Stellar Nucleosynthesis
Peter P Eggleton, David S P Dearborn, John C Lattanzio
Low-mass stars, ~1-2 solar masses, near the Main Sequence are efficient at producing He-3, which they mix into the convective envelope on the giant branch and should distribute int…
