Forging Elements in Laborites: Precise Nuclear Astrophysics Experiment in the Multi-Messenger Astronomy Era

by Prof. Xiao-Dong Tang (Institute of Modern Physics, CAS ; Joint Department for Nuclear Physics, Lanzhou University and Institute of Modern Physics, CAS)

Abstract:

Stars communicate with us via signals carried by disparate "messengers", including electromagnetic radiation, gravitational waves, neutrinos, and cosmic rays. The accurate determination of crucial nuclear reaction rates is paramount in deciphering these encoded messages, thereby revealing the hidden truths within stars and ultimately shedding light on the origins of elements. In this presentation, I will elucidate how nuclear astrophysicists synthesize elements using laboratory accelerators and study stellar nucleosynthetic processes through a review of some important experiments conducted by our group, such as the Jinping Underground Nuclear Astrophysics (JUNA) experiment, the direct measurement of the ¹²C+¹²C reaction rate, and the stellar lifetime of ⁵⁹Fe. My perspectives on experimental nuclear astrophysics will also be presented.
