Abstract

In this contribution, I will focus on two nuclides, ²⁶Al and ¹⁹F whose origin has been uncertain for a long time and still remains a matter of debate. I will present the contribution of Manuel Forestini to the understanding of the origin of these nuclides, and in particular to the description of their synthesis in asymptotic giant branch stars. I will also present an overview of the latest results concerning ²⁶Al and ¹⁹F and of the open questions still to be answered.
