Underground nuclear astrophysics at LUNA and the Bellotti Ion Beam facility of INFN-LNGS

Deep underground nuclear astrophysics with the LUNA experiment at the Gran Sasso National Laboratory by now has a 30-year history and a long track record of measuring crucial reactions for various nucleosynthesis scenarios, from the Big Bang to p-p and CNO reactions to the production of the heavy elements in the s process. With the recent installation of a 3.5 MV accelerator at the LNGS and the inauguration of the Bellotti Ion Beam Facility the stellar scenarios and astrophysically important nuclear reactions that can be investigated is expanding greatly. Recent LUNA results are presented together with the program and the experimental capabilities at the new user facility.
