Supernova remnants with magnetars: Clues to magnetar formation [PDF]

Advances in Space Research, 2008
I discuss the lack of observational evidence that magnetars are formed as rapidly rotating neutron stars. Supernova remnants containing magnetars do not show the excess of kinetic energy expected for such a formation scenario, nor is there any evidence for a relic pulsar wind nebula.

MAGNETARS: FACT OR FICTION? [PDF]

International Journal of Modern Physics E, 2011
Anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are enigmatic pulsar-like objects. The energy budget is the fundamental problem in their studies. In the magnetar model, they are supposed to be powered by the extremely strong magnetic fields (≳ 1014 G ) of neutron stars.

Searching for radio emission from radio quiet magnetars with MeerKAT

Astronomy & Astrophysics
Context. Magnetars are neutron stars that occupy the extreme end of the neutron star population, with magnetic field strengths greater than 1012 G.

Coherent Emission from Magnetars

, 2002
It is proposed that magnetospheric currents above the surfaces of magnetars radiate coherent emission in analogy to pulsars. Scaling the magnetospheric parameters suggests that the coherent emission from magnetars would emerge in the infra-red or ...

An overview of light ray deflection calculation by magnetars in nonlinear electrodynamics

Қарағанды университетінің хабаршысы. Физика сериясы
Due to the lack of experimental confirmation of the effects of nonlinear electrodynamics (NED) of vacuum on the electromagnetic wave, it remains the most pressing issue. One of the most optimal media for studying these effects, occurring in astrophysics,

Magnetic-distortion-induced ellipticity and gravitational wave radiation of neutron stars: millisecond magnetars in short GRBs, Galactic pulsars, and magnetars

, 2017
Neutron stars may sustain a non-axisymmetric deformation due to magnetic distortion and are potential sources of continuous gravitational waves (GWs) for ground-based interferometric detectors.

Origin and evolution of magnetars [PDF]

, 2008
We present a population synthesis study of the observed properties of the magnetars, which allows for X-ray selection effects, investigating the hypothesis that they are drawn from a population of progenitors that are more massive than those of the ...

Stochastic background of gravitational waves emitted by magnetars

, 2010
Two classes of high energy sources in our galaxy are believed to host magnetars, neutron stars whose emission results from the dissipation of their magnetic field.
