Abstract We discuss strange stars admixed with fermionic dark matter in the presence of a strong magnetic field using two-fluid Tolman-Oppenheimer-Volkov equations. describe quark MIT bag model and consider fields range ? 10 17 - 18 G. For matter, we cases free particles strongly self-interacting particles, fermion masses m = 5, 100, 500 GeV. effects on radii stars, as well its tidal deformabil...

Magnetars have already been a potential candidate as gravitational wave sources that could be detected by current and future terrestrial well ground based detectors. In this article, we focus on the emission from distorted rotating neutron stars. The deformation is assumed to symmetric around an axis perpendicular rotation axis. form applied in context of star whose magnetic field has deformed ...

We attempt to measure the proper motions of two magnetars — the soft gamma-ray repeater SGR 1900+14 and the anomalous X-ray pulsar 1E 2259+586 — using two epochs of Chandra observations separated by ∼ 5 yr. We perform extensive tests using these data, archival data, and simulations to verify the accuracy of our measurements and understand their limitations. We find 90% upper limits on the prope...

Observations indicate that magnetic fields on neutron stars span at least the range 10 G, corresponding to a range of magnetic fluxes similar to that found in white dwarfs and main sequence stars. The observational evidence is discussed, as well as the possible origin of the field, and the associated phenomenology (“classical”, millisecond, and binary pulsars, “magnetars”, etc.). Particular att...

A principal candidate for quiescent non-thermal gamma-ray emission from magnetars is resonant inverse Compton scattering in the strong fields of their magnetospheres. This paper outlines expectations for such emission, formed from non-thermal electrons accelerated in a pulsar-like polar cap potential upscattering thermal X-rays from the hot stellar surface. The resultant spectra are found to be...
