Neutron-rich systems are associated with a variety of important and still open questions such as: the location of neutron drip lines, the thickness of neutron skins, and the structure of neutron stars. Common to these diverse situations is the equation of state (EoS) of neutron-rich matter, namely the energy per particle in isospin-asymmetric matter as a function of density (and other...

X-ray bursts are the most frequent stellar explosions to occur throughout the cosmos and as such, represent key research environments for the field of nuclear astrophysics. These cataclysmic binary systems are known to exhibit distinctive light curves, which have now been observed with unprecedented sensitivity, that provide a detailed reflection of the underlying nuclear physics processes...
Nucleosynthesis of the p-nuclei is one of the remaining unsolved puzzles in nuclear astrophysics. One possible mechanism for production of p-nuclei is the νp-process, which is thought to occur in the ejecta of core-collapse supernovae. A recent study found that the p-p chain breakout reaction 7Be(α,γ)11C...
Classical novae are one of the most energetic stellar events in the Universe. In this site, intense γ-rays due to the beta decay of 18F produced are emitted by the HCNO cycle. The amount of 18F is determined by two destructive channels 18F(p,α)15O and 18F(p,γ)19Ne[1]. The reaction rates of the two destructive channels affect to the novae calculation model[2,3]. For this reason, many...
