On the corona of magnetars

open access: yes, 2007
Slow dissipation of non-potential magnetic fields in the magnetosphere of the magnetar is assumed to accelerate particles to hundreds MeV along the magnetic field lines. We consider interaction of fast particles with the surface of the magnetar. We argue that the collisionless dissipation does not work in the atmosphere of the neutron star because the ...

A Unified Volumetric Rate–Energy Relation from Magnetar Radio Bursts to Fast Radio Bursts

open access: yesThe Astrophysical Journal
Fast radio bursts (FRBs) are millisecond radio pulses with extremely high bright temperature. Their physical origin is still a mystery. The discovery of FRB 20020428 supports the idea that at least a portion of FRBs is generated by magnetars.

Investigating the Recursive Short X-Ray Burst Behavior of Magnetars through Crustal Interactions

open access: yesThe Astrophysical Journal
Energetic bursts from strongly magnetized neutron stars, known as magnetars, are typically detected in clusters. Once an active episode begins, anywhere from a few to thousands of hard X-ray bursts can occur over durations ranging from days to months ...

Physics of Neutron Star Crusts

open access: yesLiving Reviews in Relativity, 2008
The physics of neutron star crusts is vast, involving many different research fields, from nuclear and condensed matter physics to general relativity.

VLBA Astrometry of the Fastest-spinning Magnetar Swift J1818.0−1607: A Large Trigonometric Distance and a Small Transverse Velocity

open access: yesThe Astrophysical Journal Letters
In addition to being the most magnetic objects in the known Universe, magnetars are the only objects observed to generate fast-radio-burst-like emissions. The formation mechanism of magnetars is still highly debated and may potentially be probed with the

Modeling Isolated Magnetar Spin-down Evolution and Implications for Long-period Radio Transients

open access: yesThe Astrophysical Journal
Long-period radio transients (LPTs) are a new class of radio sources characterized by long spin periods ( P _spin  > 10 ^3 s) and highly variable radio emission. While known magnetars are relatively young ( τ   10 ^3 s.

Toward Understanding the Origin of Swift Gamma-Ray Bursts Driven by Magnetars

open access: yesThe Astrophysical Journal
In this paper, we analyze a sample of Swift gamma-ray bursts (GRBs) with extended emissions in γ -rays and/or X-ray plateaus that may be driven by magnetars.
