Descripción
Galactic 26Al is believed to be predominantly injected into
the ISM from winds and supernovae of massive stars. These stars are
typically born in groups and associations, which evolve over tens of
Myrs, and shape the interstellar medium in their surroundings.
26Al contained in stellar outflows produces a γ-ray
line at 1.809 MeV, which is potentially observable from regions of
active star formation on time scales of a few Myrs, i.e., comparable to
the mean life of 26Al. This relatively long time scale may
lead to spatial offsets between the observed 26Al γ-ray
emission and tracers of 26Al sources, such as locations of
massive-stars, HII regions, or IR emission from dust heated by
starlight. We find evidence for such an offset in star forming regions
towards Orion.
