Progenitors of Magnetars and Hyperaccreting Magnetized Disks
Yi Xie, Shuang-Nan Zhang
We propose that a magnetar could be formed during the core collapse of massive stars or coalescence of two normal neutron stars, through collecting and inheriting the magnetic fiel…
Radial Angular Momentum Transfer and Magnetic Barrier for Short-Type Gamma-Ray Burst Central Engine Activity
Tong Liu, En-Wei Liang, Wei-Min Gu +5
Soft extended emission (EE) following initial hard spikes up to 100 seconds was observed with {\em Swift}/BAT for about half of short-type gamma-ray bursts (SGRBs). This challenges…
Why do the braking indices of pulsars span a range of more than 100 millions?
Shuang-Nan Zhang, Yi Xie
Here we report that the observed braking indices of the 366 pulsars in the sample of Hobbs et al. range from about to about and are significantly correlated with th…
Testing Models of Magnetic Field Evolution of Neutron Stars with the Statistical Properties of Their Spin Evolutions
Shuang-Nan Zhang, Yi Xie
We test models for the evolution of neutron star (NS) magnetic fields (B). Our model for the evolution of the NS spin is taken from an analysis of pulsar timing noise presented by…
Quasars' Optical Polarization and Balmer Edge Feature Revealed by Ultra-Violet, and Polarized Visible to Near Infrared Emissions
Renyu Hu, Shuang-Nan Zhang
Polarized emission from a quasar is produced by wavelength-independent electron scattering surrounding its accretion disc, and thus avoid the contamination from its host galaxy and…
Blazar Anti-Sequence of Spectral Variability for Individual TeV Blazars
Jin Zhang, Shuang-Nan Zhang, En-Wei Liang
We compile from literature the broadband SEDs of twelve TeV blazars observed simultaneously or quasi-simultaneously with Fermi/LAT and other instruments. Two SEDs are available for…
