Probing the Stars: Nuclear Astrophysics with Stable and Radioactive Ion Beams — •Ragandeep Singh Sidhu — School of Mathematics and Physics, University of Surrey, Guildford GU2 7XH, United Kingdom

The elements around us, including those that make up our bodies, are forged in stars through nuclear fusion reactions. Some of these elements were first produced during the primordial Big Bang, while others continue to form in stars today. Understanding these processes involves conducting challenging experiments. These include studying reactions at extremely low energies in underground laboratories to create quiescent stellar conditions and using beams of radioactive nuclei to explore the reactions that occur in explosive events like supernovae, which involve unstable isotopes not typically found on Earth.

In this talk, I will present the current status and recent results of experiments conducted with stable and radioactive heavy-ion beams using storage rings in the GSI/FAIR laboratory in Germany. Additionally, I will discuss stable beam experiments performed underground at the Laboratory for Underground Nuclear Astrophysics in Italy and above ground at the University of Notre Dame in the USA.
