Nucleosynthesis Predictions for Intermediate-Mass AGB Stars: Comparison to Observations of Type I Planetary Nebulae
Amanda I. Karakas, Mark A. van Raai, Maria Lugaro +2
Type I planetary nebulae (PNe) have high He/H and N/O ratios and are thought to be descendants of stars with initial masses of ~3-8Msun. These characteristics indicate that the pro…
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…
Reaction rate uncertainties and 26Al in AGB silicon carbide stardust
M. A. van Raai, M. Lugaro, A. I. Karakas +1
Stardust is a class of presolar grains each of which presents an ideally uncontaminated stellar sample. Mainstream silicon carbide (SiC) stardust formed in the extended envelopes o…
Reaction rate uncertainties and the operation of the NeNa and MgAl chains during HBB in intermediate-mass AGB stars
R. G. Izzard, M. Lugaro, A. I. Karakas +2
We test the effect of proton-capture reaction rate uncertainties on the abundances of the Ne, Na, Mg and Al isotopes processed by the NeNa and MgAl chains during hot bottom burning…
The Structure of Close Binaries in Two Dimensions
R. G. Deupree, A. I. Karakas
The structure and evolution of close binary stars has been studied using the two-dimensional (2D) stellar structure algorithm developed by Deupree (1995). We have calculated a seri…
On the origin of fluorine in the Milky Way
A. Renda, Y. Fenner, B. K. Gibson +6
The main astrophysical factories of fluorine (19F) are thought to be Type II supernovae, Wolf-Rayet stars, and the asymptotic giant branch (AGB) of intermediate mass stars. We pres…
