Hypernuclear stars from relativistic Hartree-Fock density functional theory

TL;DR: In this article, the authors studied the hypernuclear matter within the relativistic Hartree-Fock theory employing several parametrizations of the hyper nuclear density functional with density dependent couplings.
Journal ArticleDOI

Probing the Nuclear Equation of State from the Existence of a ∼2.6 M⊙ Neutron Star: The GW190814 Puzzle

TL;DR: In this article, the role of the upper bound on the speed of sound is revealed, in connection with the dense nuclear matter properties, and the tidal deformability of a possible high mass candidate existing as an individual star or as a component one in a binary neutron star system.
Journal ArticleDOI

The impact of the crust equation of state on the analysis of GW170817

TL;DR: In this article, the authors re-analyze GW170817 data and establish that different crust models do not strongly impact the mass or tidal deformability of a neutron star: it is impossible to distinguish between low-density models with GW analysis.

Gravitational waves from pulsations of neutron stars described by realistic equations of state

TL;DR: In this paper, the time evolution of nonspherical perturbations of a nonrotating neutron star described by a realistic equation of state (EOS) is discussed and a constrained numerical algorithm based on standard finite-differencing schemes which permits stable and long-term evolutions.
Journal ArticleDOI

Old neutron stars as probes of isospin-violating dark matter

TL;DR: In this paper, the existence of old neutron stars limits the DM?proton scattering cross-section, especially the effects of the isospin-violating DM?nucleon interactions and the symmetry energy in the equation of state (EOS) of asymmetric nuclear matter.
