Deviation of the cross section for the nuclear reaction X(a, b)Y from the Gamow formula due to an interaction additional to the Coulomb one in the entrance channel has been analyzed[1]. It is shown that the reaction cross section has an oscillating structure at low energies. If the maximum of the first oscillation is close to the threshold of the channel a+X, it has a resonance behavior[2]. To...
Supernova remnants and compact binary mergers are prime candidates for Galactic cosmic‑ray acceleration. We have evidence that HESS J1731-347 and GW170817 have the capacity to accelerate hadrons to TeV energies and could potentially harbor strange quark matter (SQM), thereby inspiring a quest for strangelets. A transition from the 2SC to CFL phase in quark matter could release strangelets...
The dynamics of neutrinos in hot and dense magnetized stellar material, corresponding to magnetorotational supernova explosion, is considered. It is shown that taking into account fluctuations in the interaction of neutrinos with matter leads to the Fokker-Planck equation for the dynamics of the distribution function in the phase space. The component of the kinetic equation additional to the...
The softening of the equation of state of the neutron star matter upon the inclusion of hyperons, leading to a reduction in their maximum mass below the limit established by observations, named "hyperon puzzle" remains one of unresolved problems in the nuclear astrophysics. This work investigates the structure of neutron stars within the Skyrme approach. In contrast to previous studies within...
