IReNA Workshop - Progress on the reaction rates and stellar modelling affecting the 26Al abundance in the Galaxy
The radioisotope 26Al is a key observable for providing information on the role of massive stars in the Galaxy as well as on the conditions in the early Solar System. It is produced in a number of astrophysical sites, from AGB stars and Wolf-Rayet winds through to novae and supernovae. To properly interpret the observational data, it is therefore crucial to understand to the production of 26Al in these different environments. There are a number of reactions which affect the final abundance of 26Al, including (but not limited to) 25Mg(p,g)26Al, 26Al(p,g)27Si, and 26Al(n,p/a). Extensive experimental effort has been expended to improve our understanding of such key reactions and it is timely to evaluate these data to provide recommendations for the stellar models, and to focus future experimental work.
