The impact of the 18F(a,p)21Ne reaction on asymptotic giant branch nucleosynthesis
Amanda Karakas, Hye Young Lee, Maria Lugaro +2
We present detailed models of low and intermediate-mass asymptotic giant branch (AGB) stars with and without the 18F(a,p)21Ne reaction included in the nuclear network, where the ra…
Yields from single AGB stars
Amanda I. Karakas
In order to understand the composition of planetary nebulae we first need to study the nucleosynthesis occurring in the progenitor star during the thermally-pulsing Asymptotic Gian…
Stellar Models and Yields of Asymptotic Giant Branch Stars
Amanda I. Karakas, John C. Lattanzio
We present stellar yields calculated from detailed models of low and intermediate-mass asymptotic giant branch (AGB) stars. We evolve models with a range of mass from 1 to 6Msun, a…
Germanium Production in Asymptotic Giant Branch stars: Implications for Observations of Planetary Nebulae
Amanda Karakas, Maria Lugaro, Roberto Gallino
Observations of planetary nebulae (PNe) by Sterling, Dinerstein and Bowers have revealed abundances in the neutron-capture element Germanium (Ge) from solar to factors of 3 -- 10 a…
