The Self-organized Criticality Behaviors of Pulses in Magnetar Bursts

The Astrophysical Journal Supplement Series
The overall temporal and spectral characteristics (e.g., duration, fluence, peak flux, peak count rate, and total counts) of X-ray bursts (XRBs) originating from magnetars have been extensively studied to confirm their self-organized criticality (SOC ...

Magnetars: Structure and evolution from p-star models

, 2005
P-stars are compact stars made of up and down quarks in $\beta$-equilibrium with electrons in a chromomagnetic condensate. We discuss p-stars endowed with super strong dipolar magnetic field which, following consolidated tradition in literature, are ...

IXPE Observations of Magnetar Sources

Galaxies
Among the more than 60 sources observed in the first two years of operations, IXPE addressed four magnetars, neutron stars believed to host ultra-strong magnetic fields. We report here the main implication coming from IXPE measurements for the physics of

The Magnetar Connection

Proceedings of the International Astronomical Union, 2020
AbstractWe investigate the combined evolution of the dipolar surface magnetic field (Bs) and the spin-period (Ps) of known Magnetars and high magnetic field ( $${{\rm{B}}_s} \mathbin{\lower.3ex\hbox{$\buildrel>\over {\smash{\scriptstyle\sim}\vphantom{_x}}$}} {10^{13}}{\rm{G}}$$ ) radio pulsars.

Instability in Supernova Fallback Disks and Its Effect on the Formation of Ultralong Period Pulsars

The Astrophysical Journal
Several pulsars with unusually long periods were discovered recently, comprising a potential population of ultralong period pulsars (ULPPs). The origin of their long periodicity is not well understood, but may be related to magnetars spun down by ...

Braking index of PSR J1846−0258: a model of magnetic inclination evolution and its gravitational-wave implication

Frontiers in Astronomy and Space Sciences
We explain the braking index n=2.19±0.03 of PSR J1846−0258 by incorporating the time evolution of its magnetic inclination angle and dipolar magnetic field. Based on observational timing data and the age of the associated supernova remnant (tSNR≈1.77kyr),

Axion production from Landau quantization in the strong magnetic field of magnetars

Physics Letters B, 2018
We utilize an exact quantum calculation to explore axion emission from electrons and protons in the presence of the strong magnetic field of magnetars. The axion is emitted via transitions between the Landau levels generated by the strong magnetic field.

Pulsars & Magnetars [PDF]

Proceedings of the International Astronomical Union, 2008
AbstractThe largest magnetic field encountered in the observable Universe can be found in neutron stars, in particular in radio pulsars and magnetars. While recent discoveries have slowly started to blur the distinction between these two classes of highly magnetized neutron stars, it is possible that both types of sources are linked via an evolutionary
