On the recent glitch associated torque reversal of SGR 1935+2154
Wang, Weihua
The day-long timescale delayed spin-up glitch has been considered as a useful tool to probe glitch dynamics and neutron star interior physics currently. Recently, SGR 1935+2154 underwent a giant glitch during which the glitch induced positive torque exceeded the braking torque, i.e., torque reversal. We try to understand the torque reversal event from superfluid decoupling of young and high temperature pulsars. Joint analysis on delayed spin-ups from the Crab pulsar and SGR 1935 will shed light upon their physical origin(s).
