Gravitational waves from neutron star mergers and their relation to the nuclear equation of state

L Baiotti - Progress in Particle and Nuclear Physics, 2019 - Elsevier
In this article, I introduce ideas and techniques to extract information about the equation of
state of matter at very high densities from gravitational waves emitted before, during and …

Neutron star merger remnants

S Bernuzzi - General Relativity and Gravitation, 2020 - Springer
Binary neutron star mergers observations are a unique way to constrain fundamental
physics and astrophysics at the extreme. The interpretation of gravitational-wave events and …

Constraining the onset density of the hadron-quark phase transition with gravitational-wave observations

S Blacker, NUF Bastian, A Bauswein, DB Blaschke… - Physical Review D, 2020 - APS
We study the possible occurrence of the hadron-quark phase transition (PT) during the
merging of neutron star binaries by hydrodynamical simulations employing a set of …

QCD equations of state and speed of sound in neutron stars

T Kojo - AAPPS Bulletin, 2021 - Springer
Neutron stars are cosmic laboratories to study dense matter in quantum chromodynamics
(QCD). The observable mass-radius relations of neutron stars are determined by QCD …

Density functional approach to quark matter with confinement and color superconductivity

O Ivanytskyi, D Blaschke - Physical Review D, 2022 - APS
We present a novel relativistic density-functional approach to modeling quark matter with a
mechanism to mimic confinement. The quasiparticle treatment of quarks provides their …

Bayesian analysis of multimessenger MR data with interpolated hybrid EoS

A Ayriyan, D Blaschke, AG Grunfeld… - The European Physical …, 2021 - Springer
We introduce a family of equations of state (EoS) for hybrid neutron star (NS) matter that is
obtained by a two-zone parabolic interpolation between a soft hadronic EoS at low densities …

Was GW170817 a canonical neutron star merger? Bayesian analysis with a third family of compact stars

D Blaschke, A Ayriyan, DE Alvarez-Castillo… - Universe, 2020 - mdpi.com
We investigate the possibility that GW170817 was not the merger of two conventional
neutron stars (NS), but involved at least one if not two hybrid stars with a quark matter core …

Delta baryons and diquark formation in the cores of neutron stars

G Malfatti, MG Orsaria, IF Ranea-Sandoval… - Physical Review D, 2020 - APS
We investigate the hadron-quark phase transition in cold neutron stars in light of (i) the
observed limits on the maximum-mass of heavy pulsars,(ii) constraints on the tidal properties …

Twin stars as probes of the nuclear equation of state: Effects of rotation through the PSR J0952-0607 pulsar and constraints via the tidal deformability from the …

L Tsaloukidis, PS Koliogiannis, A Kanakis-Pegios… - Physical Review D, 2023 - APS
In agreement with the constantly increasing gravitational wave events, new aspects of the
internal structure of compact stars can be considered. A scenario in which a first-order …

Core-collapse supernova explosions driven by the hadron-quark phase transition as a rare r-process site

T Fischer, MR Wu, B Wehmeyer… - The Astrophysical …, 2020 - iopscience.iop.org
Supernova explosions of massive stars are one of the primary sites for the production of the
elements in the universe. Up to now, stars with zero-age main-sequence masses in the …
