A neutron star is born

DP Menezes - Universe, 2021 - mdpi.com
A neutron star was first detected as a pulsar in 1967. It is one of the most mysterious
compact objects in the universe, with a radius of the order of 10 km and masses that can …

Strange magnetars admixed with fermionic dark matter

O Ferreira, ES Fraga - Journal of Cosmology and Astroparticle …, 2023 - iopscience.iop.org
We discuss strange stars admixed with fermionic dark matter in the presence of a strong
magnetic field using the two-fluid Tolman-Oppenheimer-Volkov equations. We describe …

Density-dependent quark mass model revisited: Thermodynamic consistency, stability windows and stellar properties

BC Backes, E Hafemann, I Marzola… - Journal of Physics G …, 2021 - iopscience.iop.org
In this work a density-dependent quark model is revisited, its thermodynamic consistency
checked and the stability window for absolutely stable quark matter obtained. The …

Proto-strange quark stars from density-dependent quark mass model

A Issifu, FM da Silva, DP Menezes - The European Physical Journal C, 2024 - Springer
In this paper, we investigate the evolution of strange quark stars (SQS) from birth as proto-
strange quark stars to maturity as stable SQSs at a zero temperature. We assume that self …

Effects of strong magnetic fields on the hadron-quark deconfinement transition

BCT Backes, KD Marquezb, DP Menezes - The European Physical …, 2021 - Springer
The aim of the present work is to investigate the effects of strong magnetic fields on the
hadron-quark phase transition point at zero temperature. To describe the hadronic phase, a …

Phase transitions and latent heat in magnetized matter

MR Pelicer, DP Menezes - The European Physical Journal A, 2022 - Springer
Based on the assumption that the QCD phase diagram gives a realistic picture of hadronic
and quark matter under different regimes, it is possible to claim that a quark core may be …

Symmetry potentials and in-medium nucleon-nucleon cross sections within the Nambu–Jona-Lasinio model in relativistic impulse approximation

SN Wei, RY Yang, J Ye, N Li, WZ Jiang - Physical Review C, 2021 - APS
In the relativistic impulse approximation (RIA), we study symmetry potentials and in-medium
nucleon-nucleon (NN) cross sections with the Nambu–Jona-Lasinio (NJL) model that …

Hadron-quark phase transition at finite density in the presence of a magnetic field: Anisotropic approach

EJ Ferrer, A Hackebill - International journal of modern physics A, 2022 - World Scientific
We investigate the hadron-quark phase transition at finite density in the presence of a
magnetic field taking into account the anisotropy created by a uniform magnetic field in the …

Dark matter with chiral symmetry admixed with hadronic matterin compact stars

SN Wei, ZQ Feng - Chinese Physics C, 2022 - iopscience.iop.org
Using the two-fluid Tolman-Oppenheimer-Volkoff equation, the properties of dark matter
(DM) admixed neutron stars (DANSs) have been investigated. In contrast to previous …

Magnetic Field Effects on the Physics of Neutron Stars

AA Hackebill - 2022 - search.proquest.com
In the context of neutron stars (NS), dense-magnetized quark and hadron models have been
well studied under the assumption that the system's pressures are isotropic. However, the …
