Skyrme-Hartree-Fock-Bogoliubov mass models on a 3D mesh: V. The N2LO extension of the Skyrme EDF
G. Grams, W. Ryssens, A. Sánchez-Fernández +6
We present BSkG5, the latest entry in the Brussels-Skyrme-on-a-Grid (BSkG) series and the first large-scale nuclear structure model based on next-to-next-to-leading order (N2LO) Sk…
Neutron Star Inner Crust at Finite Temperatures: A Comparison Between Compressible Liquid Drop and Extended Thomas-Fermi Approaches
Guilherme Grams, Nikolai N. Shchechilin, Théau Diverrès +3
We investigate the effects of temperature on the properties of the inner crust of a non-accreting neutron star. To this aim, we employ two different treatments: the compressible li…
Filling fractions for the formation of nuclear pasta in neutron stars: semiclassical vs liquid-drop predictions
Nikolai N. Shchechilin, Nicolas Chamel, Andrey I. Chugunov
Historically, a sequence of nuclear pasta shapes was predicted to appear in the deepest region of the inner crust of a neutron star within the compressible liquid-drop picture, whe…
Pressure and chemical potentials in the inner crust of a cold neutron star within Hartree-Fock and extended Thomas-Fermi methods
Nicolas Chamel, Nikolai N. Shchechilin, Andrey I. Chugunov
Self-consistent mean-field methods with Skyrme-type effective interactions and semiclassical approximations, such as the Thomas-Fermi approach and its extensions are particularly w…
On variational trial functions in the extended Thomas-Fermi method
A. Y. Potekhin, A. I. Chugunov, N. N. Shchechilin +1
Parametrized nucleon density distributions are widely employed for the calculation of the properties of atomic nuclei and dense inhomogeneous matter in compact stars within the Tho…
Skyrme-Hartree-Fock-Bogoliubov mass models on a 3D mesh: IV. Improved description of the isospin dependence of pairing
Guilherme Grams, Nikolai N. Shchechilin, Adrian Sanchez-Fernandez +3
Providing reliable data on the properties of atomic nuclei and infinite nuclear matter to astrophysical applications remains extremely challenging, especially when treating both pr…
