  Supernovae provide fascinating opportunities to study various particles and
their interactions. Among these there are neutrinos, axions, and other light
weakly interacting particles, which play a significant role in our
understanding of fundamental physics. In this study, the focus lies on the
recent advancements made in characterizing axion emission from nuclear matter
within the context of supernovae. The main production mechanisms for axions
coupled with nucleons, bremsstrahlung and pion-axion conversion, are
extensively discussed. These findings shed light on the behavior of axions in
dense and hot nuclear matter, encountered in these extreme astrophysical
environments.
