Macroscopic approaches to rotating neutron stars

A. A. Uleiev, A. G. Magner, S. P. Maydanyuk +6

The macroscopic model for a neutron star (NS) as a perfect liquid drop at equilibrium is extended to rotating systems with a small frequency within the effective-surface (ES)…

Microscopic study of nuclei synthesis in pycnonuclear reaction C + C in neutron stars

S. P. Maydanyuk, Ju-Jun Xie, V. S. Vasilevsky +1

Purpose To investigate synthesis of nuclei in pycnonuclear reactions in dense medium of neutron stars on the basis of understanding, how the compound nucleus is formed during colli…

Leptodermic corrections to the TOV equations and nuclear astrophysics within the effective surface approximation

A. G. Magner, S. P. Maydanyuk, A. Bonasera +4

The macroscopic model for a neutron star (NS) as a liquid drop at the equilibrium is used to extend the Tolman-Oppenheimer-Volkoff (TOV) equations taking into account the gradient…

Neutron stars as a dense liquid drop at equilibrium within the effective surface approximation

A. G. Magner, S. P. Maydanyuk, A. Bonasera +4

The macroscopic model is formulated for a neutron star (NS) as a perfect liquid drop at the equilibrium. We use the leptodermic approximation , where is the crust thi…

Bremsstrahlung emission accompanying ternary fission of \isotope[252]{Cf}

Sergei P. Maydanyuk, Ju-Jun Xie, Sergei O. Omelchenko

\textbf{Background} In ternary fission, bremsstrahlung photons are emitted but those have never been studied yet theoretically and experimentally. In other reactions, bremsstrahlun…

Manifestation of quark effects in nuclei via bremsstrahlung analysis in the proton-nucleus scattering

Sergei P. Maydanyuk, K. Tsushima, G. Ramalho +1

\textbf{Background} (1) The incoherent emission of photons is dominant comparing to coherent one in proton-nucleus scattering. The incoherent bremsstrahlung is very sensitive to th…
