Description
Axion-like particles (ALPs) and other feebly interacting particles (FIPs) at sub-GeV scales has gen-
erated a lot of interest in the recent years.
Stars are good FIPs factories and consequently can be detected through their interaction with the
interstellar matter or decay in standard particles. Many sources are taken as target, such as the
sun and SNe.
I will illustrate how high-energy astrophysics observations can be exploited to set constraints in
ALPs model and the proposal for future indirect detection experiments on MeV gamma ray energy
range.
