چکیده

We discuss nucleosynthesis within 6 M models with Z = 0:02, 0:008 and 0:004. The emphasis is on the AGB phase of evolution, with particular reference to thermal pulses and Hot Bottom Burning. We nd strong CN cycling, with substantial Al production, especially at low metallicities.

Nucleosynthesis in Intermediate Mass Agb Stars

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 have been used to create a synthetic evolution code which calculates the nucleosynthesis very rapidly, enabling us to investigate changes in some uncertain parameters in AGB evolution, such as mass-loss and dredge-up...

Nucleosynthesis of Elements in Low to Intermediate Mass Stars through the AGB Phase

We present a review of the main phases of stellar evolution with particular emphasis on the nucleosynthesis and mixing mechanisms in lowand intermediate-mass stars. In addition to explicit studies of the effects of the first, second and third dredge-up, we also discuss cool bottom processing and hot bottom burning.

Nova nucleosynthesis and Galactic evolution of the CNO isotopes

In this paper we study the role played both by novae and single stars in enriching the interstellar medium of the Galaxy with CNO group nuclei, in the framework of a detailed successful model for the chemical evolution of both the Galactic halo and disc. First, we consider only the nucleosynthesis from single low-mass, intermediate-mass and massive stars. In particular, the nucleosynthesis pres...

The Dawes Review 2: Nucleosynthesis and stellar yields of low and intermediate-mass single stars

The chemical evolution of the Universe is governed by the chemical yields from stars, which in turn is determined primarily by the initial stellar mass. Even stars as low as 0.9M⊙ can, at low metallicity, contribute to the chemical evolution of elements. Stars less massive than about 10M⊙ experience recurrent mixing events that can significantly change the surface composition of the envelope, w...

Nucleosynthesis in Low- and Intermediate-mass Stars: an Overview

An overview of the main phases of the evolution of lowand intermediatemass stars is presented, and the different types of nucleosynthesis operating from the pre-main sequence up to and including the asymptotic giant branch phase described. The surface abundance modifications brought by each nucleosynthesis process is also briefly discussed. To appear in: Tours Symposium on Nuclear Physics III, ...
