Impact of extreme spins and mass ratios on the post-merger observables of high-mass binary neutron stars
L. Jens Papenfort, Elias R. Most, Samuel Tootle +1
The gravitational-wave events GW170817 and GW190425 have led to a number of important insights on the equation of state of dense matter and the properties of neutron stars, such as…
A new first-order formulation of the Einstein equations exploiting analogies with electrodynamics
H. Olivares, I. M. Peshkov, E. R. Most +2
The Einstein and Maxwell equations are both systems of hyperbolic equations which need to satisfy a set of elliptic constraints throughout evolution. However, while electrodynamics…
Quasi-universal behaviour of the threshold mass in unequal-mass, spinning binary neutron-star mergers
Samuel D. Tootle, L. Jens Papenfort, Elias R. Most +1
The lifetime of the remnant produced by the merger of two neutron stars can provide a wealth of information on the equation of state of nuclear matter and on the processes leading…
On accretion disks formed in MHD simulations of black hole-neutron star mergers with accurate microphysics
Elias R. Most, L. Jens Papenfort, Samuel D. Tootle +1
Remnant accretion disks formed in compact object mergers are an important ingredient in the understanding of electromagnetic afterglows of multi-messenger gravitational-wave events…
A new public code for initial data of unequal-mass, spinning compact-object binaries
L. Jens Papenfort, Samuel D. Tootle, Philippe Grandclément +2
The construction of constraint-satisfying initial data is an essential element for the numerical exploration of the dynamics of compact-object binaries. While several codes have be…
Fast ejecta as a potential way to distinguish black holes from neutron stars in high-mass gravitational-wave events
Elias R. Most, L. Jens Papenfort, Samuel Tootle +1
High-mass gravitational-wave events in the neutron-star mass range, such as GW190425, have recently started to be detected by the LIGO/Virgo detectors. If the masses of the two bin…
A lower bound on the maximum mass if the secondary in GW190814 was once a rapidly spinning neutron star
Elias R. Most, L. Jens Papenfort, Lukas R. Weih +1
The recent detection of GW190814 featured the merger of a binary with a primary having a mass of and a secondary with a mass of . While th…
On the Deconfinement Phase Transition in Neutron-Star Mergers
Elias R. Most, L. Jens Papenfort, Veronica Dexheimer +3
We study in detail the nuclear aspects of a neutron-star merger in which deconfinement to quark matter takes place. For this purpose, we make use of the Chiral Mean Field (CMF) mod…
Beyond second-order convergence in simulations of magnetised binary neutron stars with realistic microphysics
Elias R. Most, L. Jens Papenfort, Luciano Rezzolla
We investigate the impact of using high-order numerical methods to study the merger of magnetised neutron stars with finite-temperature microphysics and neutrino cooling in full ge…
Neutron-Star-Merger Equation of State
Veronica Dexheimer, Constantinos Constantinou, Elias R. Most +5
In this work, we discuss the dense matter equation of state (EOS) for the extreme range of conditions encountered in neutron stars and their mergers. The calculation of the propert…
Impact of high spins on the ejection of mass in GW170817
Elias R. Most, L. Jens Papenfort, Antonios Tsokaros +1
Following the detection of GW170817 and the accompanying kilonova AT2017gfo, it has become crucial to model and understand the various channels through which mass is ejected in neu…
Dynamical ejecta and nucleosynthetic yields from eccentric binary neutron-star mergers
L. Jens Papenfort, Roman Gold, Luciano Rezzolla
With the recent advent of multi-messenger gravitational-wave astronomy and in anticipation of more sensitive, next-generation gravitational-wave detectors, we investigate the dynam…
Signatures of quark-hadron phase transitions in general-relativistic neutron-star mergers
Elias R. Most, L. Jens Papenfort, Veronica Dexheimer +4
Merging binaries of neutron stars are not only strong sources of gravitational waves, but also have the potential of revealing states of matter at densities and temperatures not ac…
