Context. The Al-26 short-lived radioactive nuclide is the source of the observed galactic diffuse gamma-ray emission at 1.8 MeV. While different sources of Al-26 have been explored, such as asymptotic giant branch stars, massive stellar winds, and supernovae, the contribution of very massive stars h...
