Galactic radioactivities and star dust viewed from the nuclear-physics lab
Nuclear astrophysics aims at the laboratory study, both theoretical and experimental, of nuclear processes occurring in stars and responsible for the chemical enrichment of the Universe. The interplay of laboratory study and astronomical observations leads to a fruitful merging of disciplines. The talk will give an overview of recent laboratory experiments related to Galactic radioactivities observed by gamma-ray astronomy (in particular 44Ti decay from Cas A supernova remnant) and to attempts to detect on Earth short-lived nuclides as live testimony of nucleosynthesis. Current experimental developments towards better understanding of heavy-nuclide synthesis will be sketched.
