GRMHD Simulations of Accreting Proto-Magnetars II. Implications for r-process Nucleosynthesis

Tejas Prasanna, Kyle Parfrey, Brian D. Metzger +3

Newly formed, rapidly spinning, strongly magnetized neutron stars ("millisecond proto-magnetars") can arise in collapsars, neutron star mergers, or white-dwarf accretion-induced co…

GRMHD Simulations of Accreting Proto-Magnetars I. Implications for Gamma-Ray Burst Jets and Energetic Explosions

Tejas Prasanna, Kyle Parfrey, Brian D. Metzger +3

Newly formed, rapidly rotating, strongly magnetized neutron stars ("millisecond proto-magnetars") are promising central engines for gamma-ray bursts (GRBs) and luminous supernovae.…

Damping of Fast Radio Bursts in the Inner Magnetospheres of Magnetars

Siddhant Solanki, Jens Mahlmann, Alexander Philippov +1

We investigate the propagation of fast radio bursts (FRBs) through magnetar magnetospheres. Previous work showed that, in the inner magnetosphere, GHz radio waves propagate as fast…

Radio precursors of monster shocks: a mechanism for fast radio bursts from SGR 1935+2154

Andrei M. Beloborodov

Kilohertz perturbations in active magnetars evolve into monster radiative shocks at radii cm. The shock generates X-rays and a semi-coherent radio precursor, which str…

Delayed Radio Flares in Tidal Disruption Events from Star-Disk Collision Outflows

Itai Linial, Brian D. Metzger, Andrei M. Beloborodov

A growing fraction of tidal disruption events (TDEs) exhibit radio emission that rises only years after the optical or infrared flare, indicating delayed outflow activity. In some…

Global Magnetohydrodynamic Simulations of Monster Shocks in Neutron Star Magnetospheres

Michael P. Grehan, Bart Ripperda, Andrei M. Beloborodov +2

Waves launched from the neutron star surface or inner magnetosphere propagate through the magnetosphere as small perturbations, but can grow relative to the background magnetic fie…

Relativistic Magnetohydrodynamic Simulations of Giant Magnetar Bursts

Koushik Chatterjee, Alexander Philippov, Andrei M. Beloborodov +3

Gradual crustal deformation can generate strongly twisted magnetic fields around magnetars, potentially triggering giant flares with total energies exceeding $10^{44}\,\mathrm{erg}…

Hyperactive Magnetar Eruptions: Giant Flares, Baryon Ejections, and Fast Radio Bursts

Ashley Bransgrove, Andrei M. Beloborodov, Yuri Levin

Young neutron stars born with magnetic fields G become hyperactive as the field inside the star evolves through ambipolar diffusion on a timescale s.…

The High Energy X-ray Probe (HEX-P): Magnetars and Other Isolated Neutron Stars

J. A. J. Alford, G. A. Younes, Z. Wadiasingh +23

The hard X-ray emission from magnetars and other isolated neutron stars remains under-explored. An instrument with higher sensitivity to hard X-rays is critical to understanding th…

Magnetars

Victoria M. Kaspi, Andrei Beloborodov

Magnetars are young and highly magnetized neutron stars which display a wide array of X-ray activity including short bursts, large outbursts, giant flares and quasi-periodic oscill…
