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 $B\gtrsim 10^{16}$ G become hyperactive as the field inside the star evolves through ambipolar diffusion on a timescale $\sim 10^9$ s.…
