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

open access: yesEPJ 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

Equations of State for Hadronic Matter and Mass-Radius Relations of Neutron Stars with Strong Magnetic Fields

open access: yesUniverse, 2022
Neutron star is an important object for us to verify the equation of state of hadronic matter. For a specific choice of equations of state, mass and radius of a neutron star are determined, for which there are constraints from observations.

Spontaneous scalarization in proto-neutron stars

open access: yesEuropean 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.

Radiation from axion star-neutron star binaries with a tilted rotation axis in the presence of plasma

open access: yesJournal of High Energy Physics, 2022
We investigate the form of the radiation emitted by an axion star-neutron star binary using a f(r) = sech(r/R) profile for the axion star. Our analysis takes into account the co-rotating plasma of the neutron star.

Hyperons in Neutron Stars

open access: yesUniverse, 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

Inferring the dense nuclear matter equation of state with neutron star tides [PDF]

open access: yesEPJ Web of Conferences, 2022
During the late stages of a neutron star binary inspiral finite-size effects come into play, with the tidal deformability of the supranuclear density matter leaving an imprint on the gravitational-wave signal.

Nuclear Physics with Gravitational Waves from Neutron Stars Disrupted by Black Holes

open access: yesThe Astrophysical Journal Letters, 2023
Gravitational waves from neutron star–black hole (NSBH) mergers that undergo tidal disruption provide a potential avenue to study the equation of state of neutron stars and hence the behavior of matter at its most extreme densities.

Thermodynamics of Hot Neutron Stars and Universal Relations

open access: yesUniverse, 2022
Over the last few years, the detection of gravitational waves from binary neutron star systems has rekindled our hopes for a deeper understanding of the unknown nature of ultradense matter.

Semi-empirical relation to understand matter properties at neutron star interiors

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
The occurrence of quark matter at the center of neutron stars is still in debate. This study defines some semi-empirical parameters that try to quantify the presence and the amount of quark matter at star interiors.

Experimental Challenge to Heavy Element Synthesis under Explosive Burning on Neutron Stars [PDF]

open access: yesEPJ Web of Conferences, 2020
Binary stellar systems that involve a neutron star or two neutron stars make interesting phenomena, X-ray bursts and kilo-novae, respectively, which involve explosive burning either in the proton-rich environment or in the neutron-rich environment. These
