Explaining radio emission of magnetars via rotating and oscillating magnetospheres of neutron stars
MHD: pulsars — general — relativity — oscillations — magnetar — stars:neutron — death line — plasma magnetosphere
2011/10/10
We investigate the conditions for radio emission in rotating and oscillating magnetars, by focusing on the main physical processes determining the position of their death-lines in the P-\dot{P} diagra...
Soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are thought to be magnetars:
neutron stars powered by extreme magnetic elds. These rare objects are characterized by repeated and somet...

Magneto-elastic torsional oscillations magnetars
2010/12/21
We extend a general-relativistic ideal magneto-hydrodynamical code to include the effects of elasticity. Using this numerical tool we analyse the magneto-elastic oscillations of highly magnetised neut...

2010/11/15
Neutron stars can have, in some phases of their life, extremely strong magnetic fields, up to 1015−16 G. These objects, named magnetars, could be powerful sources of gravitational waves, since t...

2010/11/9
We report on the search for 0.1{10 GeV emission from magnetars in 17 months of Fermi Large
Area Telescope (LAT) observations. No signi cant evidence for gamma-ray emission from any of the currently-k...
Magnetars as Highly Magnetized Quark Stars: an analytical treatment
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
We present an analytical model of a magnetar as a high density magnetized quark bag. The effect of strong magnetic fields (B > 5 x 10^{16} G) in the equation of state is considered. An analytic expres...
