Scientific paper

The main points discussed in this paper are the following. (1) We show the importance of applying a consistent procedure to deduce from the observed data the quantity of Al-26 present in the Galaxy. (2) We present the results of the most recent theoretical models for the different sources of Al-26. (3) Since from the point of view of the theoretical models, neither a young (massive) population of stars nor an old (low-mass) one can be excluded as the main source of the Galactic Al-26, we have to look for clear observable signatures of the site where this element is synthesized. The results of recent work on this subject will be reported. (4) Finally, we present some constraints on the possible sources derived from simple models for the chemical evolution of the Galaxy.
