Binary neutron star mergers within kaon condensation:GW170817

چکیده
The equation of state (EoS) neutron star (NS) matter is investigated considering kaon condensation. Moreover, the tidal parameters related to components binary mergers are determined and compared constraints GW170817 imposed on these quantities. In this study, we employ lowest-order constrained variational (LOCV) approach utilize {AV6$'$, AV8$'$, AV18 potentials} accompanied by three nucleon interaction (TNI) {in order consider nucleon-nucleon interaction}. It known that existence kaons in core NSs softens EoS {and thus} lowers value maximum mass which expected be greater than 2 M$_\odot$. Our results demonstrate condensation with a strangeness value, a$_{3}$m$_s$=-134 MeV satisfies constraint except for AV8$'$+TNI potential. However, calculation dimensionless deformability shows decrease gets less deformed.

Binary Neutron Star Mergers
We review the current status of studies of the coalescence of binary neutron star systems. We begin with a discussion of the formation channels of merging binaries and we discuss the most recent theoretical predictions for merger rates. Next, we turn to the quasi-equilibrium formalisms that are used to study binaries prior to the merger phase and to generate initial data for fully dynamical sim...
متن کاملThe Fate of Neutron Star Binary Mergers
Following merger, a neutron star (NS) binary can produce roughly one of three different outcomes: (1) a stable NS, (2) a black hole (BH), or (3) a supra-massive, rotationally-supported NS, which then collapses to a BH following angular momentum losses. Which of these fates occur and in what proportion has important implications for the electromagnetic transient associated with the mergers and t...
متن کاملDynamical Mass Ejection from Binary Neutron Star Mergers
We present fully general-relativistic simulations of binary neutron star mergers with a temperature and composition dependent nuclear equation of state. We study the dynamical mass ejection from both quasi-circular and dynamical-capture eccentric mergers. We systematically vary the level of our treatment of the microphysics to isolate the effects of neutrino cooling and heating and we compute t...
متن کاملBinary neutron star mergers in fully general relativistic simulations
We perform 3D numerical simulations for merger of equal mass binary neutron stars in full general relativity preparing irrotational binary neutron stars in a quasiequilibrium state as initial conditions. Simulations have been carried out for a wide range of stiffness of equations of state and compactness of neutron stars, paying particular attention to the final products and gravitational waves...
متن کاملEffects of hyperons in binary neutron star mergers.
Numerical simulations for the merger of binary neutron stars are performed in full general relativity incorporating both nucleonic and hyperonic finite-temperature equations of state (EOS) and neutrino cooling. It is found that even for the hyperonic EOS, a hypermassive neutron star is first formed after the merger for the typical total mass ≈2.7M(⊙), and subsequently collapses to a black hole ...
