Exploring Superfluid Angular Momentum Reservoir Effect on Pulsar Glitches and Forecasting Next Glitches of the Crab Pulsar
Pei-Xin Zhu, Xiao-Ping Zheng, Quan Cheng +2
Pulsar glitches are generally viewed as stochastic events driven by sudden angular momentum transfer from the neutron star's superfluid interior to its crust. Except two peculiar p…
Superfluid Angular Momentum Reservoir Effect in Pulsar Glitches and Crab Pulsar Glitch Time Prediction
Pei-Xin Zhu, Xiao-Ping Zheng, Quan Cheng +2
Pulsar glitches are usually regarded as stochastic, independent events triggered by sudden angular momentum transfer from the neutron star's superfluid interior to its crust. Howev…
Secular Evolution of PSR J2021+4026: Long-Term γ-Ray Flux and Spin-Down Variability Beyond State Transitions
Xue-Zhi Liu, Ming-Yu Ge, Xiao-Ping Zheng +7
PSR J2021+4026 is a remarkable -ray pulsar exhibiting repeated transitions between high -ray flux (HGF) and low -ray flux (LGF) states. With 17-yr Fermi-LAT monitoring,…
The persistent shift in spin-down rate following the largest Crab pulsar glitch rules out external torque variations due to starquakes
Xiao-Ping Zheng, Wei-Hua Wang, Chun Huang +2
It was previously believed that, the long-term persistent increase in the spin-down rate of the Crab pulsar following a glitch is direct evidence of a starquake-induced glitch or a…
Glitches and glitching clusters in rotation-powered pulsars
Pei-Xin Zhu, Xiao-Ping Zheng
The study of pulsar glitch phenomena serves as a valuable probe into the dynamic properties of matter under extreme high-density conditions, offering insights into the physics with…
