Spontaneous scalarization in proto-neutron stars [PDF]

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.

Hyperons in Neutron Stars [PDF]

Universe, 2021
I review the issues related to the appearance of hyperons in neutron star matter, focusing in particular on the problem of the maximum mass supported by hyperonic equations of state. I discuss the general mechanism that leads to the formation of hyperons

Superfluid neutron stars [PDF]

The Ninth Marcel Grossmann Meeting, 2001
Neutron stars are believed to contain (neutron and proton) superfluids. I will give a summary of a macroscopic description of the interior of neutron stars, in a formulation which is general relativistic. I will also present recent results on the oscillations of neutron stars, with superfluidity explicitly taken into account, which leads in particular ...

PSR J0952−0607: The Fastest and Heaviest Known Galactic Neutron Star [PDF]

Astrophysical Journal Letters, 2022
We describe Keck-telescope spectrophotometry and imaging of the companion of the “black widow” pulsar PSR J0952−0607, the fastest known spinning neutron star (NS) in the disk of the Milky Way. The companion is very faint at minimum brightness, presenting

Constraints on the Dense Matter Equation of State and Neutron Star Properties from NICER’s Mass–Radius Estimate of PSR J0740+6620 and Multimessenger Observations [PDF]

Astrophysical Journal Letters, 2021
In recent years our understanding of the dense matter equation of state (EOS) of neutron stars has significantly improved by analyzing multimessenger data from radio/X-ray pulsars, gravitational wave events, and from nuclear physics constraints.

Cooling of neutron stars with quark-hadron continuity [PDF]

EPJ Web of Conferences, 2022
Neutron stars are high-density objects formed by the gravitational collapse of massive stars, and the whole star can be likened to a giant nucleus. The interior of a neutron star is considered to contain exotic particles and states which do not appear in
