We investigate the influence of magnetic fields upon the dynamics of, and resulting gravitational waves from, a binary neutron-star merger in full general relativity coupled to ideal magnetohydrodynamics. We consider two merger scenarios: one where the stars have aligned poloidal magnetic fields and one without. Both mergers result in a strongly differentially rotating object. In comparison to the nonmagnetized scenario, the aligned magnetic fields delay the full merger of the stars. During and…

Linking electromagnetic and gravitational radiation in coalescing binary neutron stars
We expand on our study of the gravitational and electromagnetic emissions from the late stage of an inspiraling neutron star binary as presented in Palenzuela et al. [Phys. Rev. Lett. 111, 061105
Gravitational Radiation from Collapsing Magnetized Dust. II -- Polar Parity Perturbation --
Using gauge-invariant perturbation theory, we study the effects of stellar magnetic fields on polar gravitational waves emitted during the collapse of homogeneous dust. We found that the emitted
General relativistic simulations of black-hole-neutron-star mergers: Effects of magnetic fields
As a neutron star (NS) is tidally disrupted by a black hole (BH) companion at the end of a BH-NS binary inspiral, its magnetic fields will be stretched and amplified. If sufficiently strong, these
Magnetorotational instability in neutron star mergers: impact of neutrinos
The merger of two neutron stars may give birth to a long-lived hypermassive neutron star. If it harbours a strong magnetic field of magnetar strength, its spin-down could explain several features of
Producing Magnetar Magnetic Fields in the Merger of Binary Neutron Stars
The merger of binary neutron stars (BNSs) can lead to large amplifications of the magnetic field due to the development of turbulence and instabilities in the fluid, such as the Kelvin-Helmholtz
Can magnetic fields be detected during the inspiral of binary neutron stars
Using accurate and fully general-relativistic simulations we assess the effect that magnetic fields have on the gravitational-wave emission produced during the inspiral and merger of magnetized
Gravitational and electromagnetic emission by magnetized coalescing binary systems
We discuss the possibility to obtain an electromagnetic emission accompanying the gravitational waves emitted in the coalescence of a compact binary system. Motivated by the existence of black hole
General Relativistic Magnetohydrodynamic Simulations of Binary Neutron Star Mergers with the APR4 Equation of State
We present new results of fully general relativistic magnetohydrodynamic simulations of binary neutron star (BNS) mergers performed with the Whisky code. All the models use a piecewise polytropic
Binary neutron star mergers: a review of Einstein's richest laboratory.
The recent progress in understanding what could be considered Einstein's richest laboratory is reviewed, highlighting in particular the numerous significant advances of the last decade in models, techniques and results for fully general-relativistic dynamical simulations.
Gravitational Waves from Merging Binary Neutron-Star Systems
The merger of binary neutron-star systems is among the scientifically richest events in the universe: it involves extremes of matter and gravity, copious emission of gravitational waves, complex


Producing Ultrastrong Magnetic Fields in Neutron Star Mergers
We report an extremely rapid mechanism for magnetic field amplification during the merger of a binary neutron star system. This has implications for the production of the short class of gamma-ray

Collapse of magnetized hypermassive neutron stars in general relativity.
Hypermassive neutron stars (HMNSs)--equilibrium configurations supported against collapse by rapid differential rotation--are possible transient remnants of binary neutron-star mergers. Using newly
Formation of very strongly magnetized neutron stars - Implications for gamma-ray bursts
It is proposed that the main observational signature of magnetars, high-field neutron stars, is gamma-ray bursts powered by their vast reservoirs of magnetic energy. If they acquire large recoils,

We model two mergers of orbiting binary neutron stars, the first forming a black hole and the second a differentially rotating neutron star. We extract gravitational waveforms in the wave zone.
Gravitational radiation from collapsing magnetized dust
In this article we study the influence of magnetic fields on the axial gravitational waves emitted during the collapse of a homogeneous dust sphere. We found that while the energy emitted depends

During accretion, a neutron star (NS) is spun up as angular momentum is transported through its surface layers. We study the resulting differentially rotating profile, focusing on the impact this has
