A deep understanding of the dynamics of Binary Neutron Star (BNS) mergers requires a detailed treatment of the relativistic hydrodynamics of the merger, as well as of the microphysics governing the underlying electromagnetic, strong and weak interactions. Accurate numerical simulations are pivotal to correctly interpret the data collected through the detection of gravitational waves and...
Over the last few years, several processes relevant to the CNO, MgAl and NeNa cycles have been studied using the LUNA 400 kV machine and I will report about few recent results. By the end of 2022 LNGS is planning to conclude installation and commissioning of the new 3.5 MV accelerator. This investment is allocated in the context of the Progetto Premiale "LUNA-MV”. LUNA has been measuring cross...
Abundance of carbon and oxygen in the universe is one of the main questions of Nuclear Astrophysics. Its knowledge is strictly bound to the detrmination of the reaction rate of $^{12}C(\alpha,\gamma)^{16}O$ which heavily influences star evolution.\
At the energy of astrophysical interest ($\sim$300 keV) multiple transitions contribute to the cross section and its absolute value is too low...
The $^{17}$O(n,$\alpha$)$^{14}$C reaction is considered in astrophysical codes for its role in the astrophysically relevant "s(slow)-process" since it could act as a possible “neutron-poison” for the neutron induced nucleosynthesis thus influencing the final stellar abundances of some elements such as Fe, Ni or Sr. Thus, its reaction rate must be known in the energy region of interest for...
