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…
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.…
