From stars to underground labs: Nuclear astrophysics measurements at Felsenkeller — •Eliana Masha — Helmholtz-Zentrum Dresden-Rossendorf (HZDR)

Nuclear reactions in stars take place at very low energies and are characterized by extremely small cross sections. To reproduce these conditions in the laboratory, high-intensity ion beams and low background environments are required. Underground accelerator laboratories provide such conditions by suppressing cosmic-ray induced background, enabling direct measurements at relevant astrophysical energies. This approach was pioneered by the LUNA experiment at Gran Sasso and has since been extended to other underground facilities worldwide. Among them, the Felsenkeller laboratory in Dresden offers new opportunities for precision nuclear cross-section measurements for different astrophysical scenarios. This talk will introduce the connection between nuclear processes in stars and underground laboratory experiments, and present selected science cases from the Felsenkeller laboratory.
