Grain Boundary Diffusion in Yukawa Crystals
Matthew E. Caplan, Nevin T. Smith, Dany Yaacoub +3
We present calculations of diffusion coefficients in grain boundaries in Yukawa crystals for astrophysics. Our methods follow from our recent work calculating diffusion coefficient…

Crustal Quakes Spark Magnetospheric Blasts: Imprints of Realistic Magnetar Crust Oscillations on the Fast Radio Burst Signal
Louis Burnaz, Elias R. Most, Ashley Bransgrove
Many transients believed to originate from magnetars are thought to be triggered by crustal activity, which feeds back on the surrounding magnetosphere. These perturbations, throug…

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.…
