Abstract :
The closest Wolf-Rayet star, WR 11 in the binary system γ2 Velorum, is the only star for which the spectral signature of the 26Al produced in its core is expected to be detectable with current gamma-ray instruments, through the 1.8 MeV gamma-ray line produced by the radioactive decay of the 26Al nuclei.
We present here the current status of both model predictions, from calculations of massive star evolution including rotation of stellar interior, and from data on γ2 Velorum obtained by the ESAʹs gamma-ray satellite INTEGRAL over the first year of its mission.
