Abstract
Aluminium-26 is a radioactive isotope present in the early Solar System and in the current Galaxy. The most likely places for the production of this isotope are massive stars, single and binary. We simulated a single star of 20 M\( _{\odot } \) with the MESA code, as well as binaries consisting of 20 + 18 M\( _{\odot } \) stars. From these simulations, it becomes clear that binaries give higher \(^{26}\)Al yields than single stars.
