Progress on nuclear reaction rates affecting the stellar production of ²⁶Al

Abstract The radioisotope 26 Al is a key observable for nucleosynthesis in the Galaxy and environment of early Solar System. To properly interpret large variety astronomical meteoritic data, it crucial to understand both nuclear reactions involved production relevant stellar sites physics such sites. These range from winds low- intermediate-mass asymptotic giant branch stars; massive very stars, their Wolf–Rayet final core-collapse supernovae (CCSN); ejecta novae, explosions that occur on surface white dwarf accreting material companion. Several affect these astrophysical objects, including (but not limited to) 25 Mg( p , γ ) Al, Al( 27 Si, n / α ). Extensive experimental effort has been spent during recent years improve our understanding reactions. Here we present summary motivation study review its different sites, timely evaluation currently available data. We also provide recommendations input into models suggest relevant, future work.
