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.

Multi-Wavelength Polarimetry of Isolated Neutron Stars
Galaxies, 2018 Isolated neutron stars are known to be endowed with extreme magnetic fields, whose maximum intensity ranges from 10 12 – 10 15 G, which permeates their magnetospheres. Their surrounding environment is also strongly magnetized, especially in

Constraints on physics of neutron stars from X-ray observations [PDF]
, 2013 I summarize some constraints on the physics of neutron stars arising from X-ray observations of the surfaces of neutron stars, focusing on using models of low-magnetic-field neutron star atmospheres to interpret their X-ray spectra.

Many Aspects of Magnetic Fields in Neutron Stars
Universe, 2018 In this work, we explore different aspects in which strong magnetic fields play a role in the composition, structure and evolution of neutron stars. More specifically, we discuss (i) how strong magnetic fields change the equation of state of dense matter,

Rapidly rotating neutron stars in $$f(R,T)=R+2 \lambda T$$ f ( R , T ) = R + 2 λ T gravity
European Physical Journal C: Particles and Fields, 2023 In this work, we study the influence of f(R, T) gravity on rapidly rotating neutron stars. First we discuss the main aspects of this modified theory of gravity where the gravitational Lagrangian is an arbitrary function of the Ricci scalar R and of the ...

Evolution of Neutron Star Magnetic Fields
Universe, 2021 Neutron stars are natural physical laboratories allowing us to study a plethora of phenomena in extreme conditions. In particular, these compact objects can have very strong magnetic fields with non-trivial origin and evolution.

Neutron stars and strange stars in the chiral SU(3) quark mean field model [PDF]
, 2005 We investigate the equations of state for pure neutron matter and strange hadronic matter in $\beta$-equilibrium, including $\Lambda$, $\Sigma$ and $\Xi$ hyperons. The masses and radii of pure neutron stars and strange hadronic stars are obtained.

Neutron skins and neutron stars [PDF]
AIP Conference Proceedings, 2013 The neutron-skin thickness of heavy nuclei provides a fundamental link to the equation of state of neutron-rich matter, and hence to the properties of neutron stars. The Lead Radius Experiment ("PREX") at Jefferson Laboratory has recently provided the first model-independence evidence on the existence of a neutron-rich skin in 208Pb.

Boson and neutron stars with increased density
Physics Letters B, 2020 We discuss boson stars and neutron stars, respectively, in a scalar-tensor gravity model with an explicitly time-dependent real scalar field. While the boson stars in our model – in contrast to the neutron stars – do not possess a hard core, we find that
