Finite-temperature equation of state with hyperons [PDF]
EPJ Web of Conferences, 2022 We present the novel finite-temperature FSU2H* equation-of-state model that covers a wide range of temperatures and lepton fractions for the conditions in proto-neutron stars, neutron star mergers and supernovae.

Temperature Distribution in Magnetized Neutron Star Crusts [PDF]
Astronomy & Astrophysics, 2004 We investigate the influence of different magnetic field configurations on the temperature distribution in neutron star crusts. We consider axisymmetric dipolar fields which are either restricted to the stellar crust, ``crustal fields'', or allowed to penetrate the core, ``core fields''. By integrating the two-dimensional heat transport equation in the

Spontaneous scalarization in proto-neutron stars
European Physical Journal C: Particles and Fields, 2023 Proto-neutron stars are born when a highly evolved and massive star collapses under gravity. In this paper, we investigate the spontaneous scalarization in proto-neutron stars.

Brazilian Journal of Radiation Sciences, 2022 In this work, the Neutron Point Kinetics equations are solved for six groups of delayed neutron precursors and different types of ramp reactivity, considering the temperature effects by the Rosenbrock’s method, to verify the methodology. Furthermore, the

The neutron moderation theory, taking into account a moderating medium temperature
Trudy Odesskogo Politehničeskogo Universiteta, 2017 In this paper, in the framework of the gas model, based on the solution of the kinematic problem of the neutron elastic scattering on the nucleus in the “L” system in the general case, that is, when prior to the scattering not only the neutron, but also

Decoupling of a neutron interferometer from temperature gradients
Review of Scientific Instruments, 2016 Neutron interferometry enables precision measurements that are typically operated within elaborate, multi-layered facilities which provide substantial shielding from environmental noise. These facilities are necessary to maintain the coherence requirements in a perfect crystal neutron interferometer which is extremely sensitive to local environmental ...

Neutron matter at finite temperature [PDF]
Nuclear Physics A, 2008 We calculate the neutron matter equation of state at finite temperature based on low-momentum two- and three-nucleon interactions. The free energy is obtained from a loop expansion around the Hartree-Fock energy, including contributions from normal and anomalous diagrams.

Investigation on the heat resistance of neutron shielding materials for reactor cavity
He jishu, 2021 BackgroundHigh temperature neutron shielding of the reactor cavity in the third generation nuclear power plant requires a high temperature resistant shielding material, but there is no suitable material that meets the design requirements in the market ...
