The imprint of the equation of state on the axial w‐modes of oscillating neutron stars

TL;DR: In this article, the dependence of the pulsation frequencies of the axial quasi-normal modes of a non-rotating neutron star upon the equation of state describing the star interior was discussed.

Quark-hadron phase transitions in Young and old neutron stars

TL;DR: In this article, the mixed phase of quarks and hadrons in the dense matter encountered in the varying conditions of temperature and trapped neutrino fraction in proto-neutron stars is studied.

GW190814's Secondary Component with Mass 2.50–2.67 M⊙ as a Superfast Pulsar

TL;DR: Using Stergioulas's RNS code for investigating fast pulsars with Equation of States (EOSs) on the causality surface (where the speed of sound equals that of light) of the high-density EOS parameter space satisfying all known constraints from both nuclear physics and astrophysics, this article showed that one possible explanation for the GW190814's secondary component of mass $(2.50-2.67)$ M$

Roles of Hyperons in Neutron Stars

TL;DR: In this article, the role of hyperons in the cores of neutron stars was examined, and it was shown that hyperons not only softens the equation of state but also severely constrains its values at high densities, and the valid range for the maximum neutron star mass is limited to about 1.5-1.8 $M_\odot$, which is a much narrower range than available when hyperon formation is ignored.

Upper limits on the observational effects of nuclear pasta in neutron stars

TL;DR: In this paper, the effects of nuclear shapes at the bottom of the inner crust of the neutron star inner crust -nuclear "pasta" - on observational phenomena are estimated by comparing the limiting cases that those phases have a vanishing shear modulus and that they have the shear modulation of a crystalline solid.
