Mg and Al Yields from Low and Intermediate Mass AGB stars
A. I. Karakas, J. C. Lattanzio
We investigate the production of aluminium and the heavy magnesium isotopes in asymptotic giant branch models. We evolve models with a wide range in initial mass (between 1 and 6Ms…
Nucleosynthesis in intermediate mass AGB stars
John Lattanzio, Corinne Charbonnel, Manuel Forestini
We present a summary of the main sites for nucleosynthesis in intermediate mass Asymptotic Giant Branch (AGB) stars. We then discuss some detailed evolutionary models and how these…
Gravonuclear Instabilities in Post-Horizontal-Branch Stars
Allen V. Sweigart, John C. Lattanzio, James P. Gray +1
We investigate the gravonuclear instabilities reported by Bono et al. (1997a,b) during the onset of helium-shell burning at the end of the horizontal-branch (HB) phase. These insta…
Nucleosynthesis in Intermediate-Mass Asymptotic Giant Branch Stars
John C. Lattanzio
We summarise the main properties of Asymptotic Giant Branch stars, including their structure, evolution and nucleosynthesis. The main physical mechanisms are outlined, as are the u…
Degenerate thermal pulses in AGB stars
Cheryl Frost, John Lattanzio, Peter Wood
We report on the discovery of a new kind of thermal pulse in intermediate mass AGB stars. Deep dredge-up during normal thermal pulses on the AGB leads to the formation of a long, u…
The Brightest Carbon Stars
Cheryl Frost, Robert Cannon, John Lattanzio +2
It is currently accepted that Hot-Bottom-Burning (HBB) in intermediate-mass asymptotic giant branch (AGB) stars prevents the formation of C~stars. Nevertheless, we present in this…
