The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

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 6Msun), and composition (Z=0.02, 0.008, 0.004). We evolve the models from the pre-main sequence, through all intermediate stages including the core helium flash, to near the end of the thermally-pulsing AGB phase. We performed detailed nucleosynthesis calculations from which we determine for the first time, the production of the magnesium and aluminium isotopes as a function of the stellar mass and composition. From our models, we calculate stellar yields suitable for galactic chemical evolution models. The most massive AGB models produce the neutron-rich magnesium isotopes, and also produce Al-26 in substantial quantities via hot bottom burning. We note that the calculations are subject to many uncertainties, such as the modelling of the third dredge up, mass-loss and nuclear reaction rates.
