Description

Nuclear fusion reactions within stars generate the energy and forge the elements observed throughout the Universe. These reactions transform primordial hydrogen and helium remnants from the Big Bang into a diverse array of elements. Nuclear astrophysics provides unique insights into the nuclear processes involved in astrophysical environments and responsible for the nucleosynthesis of the elements. Studying these processes is challenging due to the small cross section in the relevant energy range, known as the Gamow window, and the very low counting rate at such low energy.
By investigating these reactions, primordial nucleosynthesis as well as the composition and evolution of stars can be unraveled, shedding light on the intricate mechanisms behind the chemical evolution of the Universe. Complimentary approaches involving both direct and indirect measurements enable the investigation of nuclear reactions in the Gamow window, often exploiting particular conditions.
This talk highlights the most significant methods of nuclear astrophysics and shows some of the ongoing experimental efforts in unraveling the secrets of nuclear reactions that shape our Universe.
