PSR J0030+0451 Mass and Radius from NICER Data and Implications for the Properties of Neutron Star Matter [PDF]
Astrophysical Journal, 2019 Neutron stars are not only of astrophysical interest, but are also of great interest to nuclear physicists because their attributes can be used to determine the properties of the dense matter in their cores.

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

New temperature dependent hyperonic equation of state: Application to rotating neutron star models and I -Q relations [PDF]
, 2017 In this work we present a newly constructed equation of state (EoS), applicable to stellar core collapse and neutron star mergers including the entire baryon octet.

Transition density and pressure in hot neutron stars [PDF]
, 2010 Using the momentum-dependent MDI effective interaction for nucleons, we have studied the transition density and pressure at the boundary between the inner crust and liquid core of hot neutron stars.

Bulk Viscous Damping of Density Oscillations in Neutron Star Mergers [PDF]
Particles, 2020 In this paper, we discuss the damping of density oscillations in dense nuclear matter in the temperature range relevant to neutron star mergers. This damping is due to bulk viscosity arising from the weak interaction “Urca” processes of neutron decay and

Signatures of Quark-Hadron Phase Transitions in General-Relativistic Neutron-Star Mergers. [PDF]
Physical Review Letters, 2018 Merging binaries of neutron-stars are not only strong sources of gravitational waves, but also have the potential of revealing states of matter at densities and temperatures not accessible in laboratories.

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
