LUNA: Present and Future of Nuclear Astrophysics at LNGS featuring Federico Ferraro (LNGS) (Opens in a new window)

Online

Seminars

Hosted by: Denise Piatti (University of Padova)

The LUNA (Laboratory for Underground Nuclear Astrophysics) experiment is located at the LNGS (Laboratori Nazionali del Gran Sasso) in Italy. LUNA is aimed at studying the nuclear reactions that are responsible for the synthesis of the elements and shape the life of stars in the universe. The reduction of the cosmic-rays induced background provided by the 1400 m thick rock overburden at LNGS allows the direct measurement of the cross section in the energy range relevant to astrophysics.

Spectroscopic observations as tracers of stellar nucleosynthesis featuring Shreeya Shetye (KU Leuven) (Opens in a new window)

Online

Seminars

Hosted by: Thibaut Dumont (CNRS Strasbourg)

The groundwork for stellar nucleosynthesis was established over 70 years ago, marking the beginning of a fascinating journey. Since then, substantial progress has unfolded on both theoretical and observational fronts. On the theoretical side, intricate models of stellar evolution and nucleosynthesis have evolved, utilising increasingly precise nuclear data. Simultaneously, the observational realm has witnessed a significant rise in the number of stars analysed.

The n-process in Core-Collapse Supernovae featuring Marco Pignatari (Konkoly Observatory) (Opens in a new window)

Online

Seminars

The n-process is a neutron-capture process activated in Core-Collapse Supernovae (CCSNe), when the Supernova shock is passing through the deepest He-rich layers of the massive star progenitor. The peak neutron density generated is typically larger than 1018 neutrons cm-3, and the dominant neutron source is the Ne22(alpha,n)Mg25 reaction where the Ne22 available was left in the ashes of the hydrostatic convective He shell.
