There has recently been growing evidence for the existence of neutron stars possessing
magnetic fields with strengths that exceed the quantum critical field strength of 4.4× 10 13 G …

The study of pulsars in the three and a half decades since their discovery has highlighted a
handful of issues critical to their understanding. To date there is no consensus on the …

We investigate the production of electron-positron pairs by inverse Compton scattered (ICS)
photons above a pulsar polar cap (PC) and calculate surface heating by returning positrons …

The absence of radio pulsars with long periods has lead to the popular notion of a high-P"
death line." In the standard picture, beyond this boundary, pulsars with low spin rates cannot …

Resonant cyclotron scattering of the surface radiation in the magnetospheres of neutron
stars may considerably modify the emergent spectra and impede efforts to constrain neutron …

A significant new development in the study of Anomalous X-ray Pulsars (AXPs) has been the
recent discovery by INTEGRAL and RXTE of flat, hard X-ray components in three AXPs …

Recent calculations indicate that the cohesive energy of condensed matter increases with
magnetic field strength and becomes very significant at magnetar-like fields (eg 10 keV at 3× …

We present numerical simulations of electron–positron pair cascades in the
magnetospheres of magnetic neutron stars for a wide range of surface fields (B p= 1012 …

Hard, nonthermal, persistent pulsed X-ray emission extending between 10 and∼ 150 keV
has been observed in nearly 10 magnetars. For inner-magnetospheric models of such …

4U 0142+ 61 is one of the Anomalous X-ray Pulsars exhibiting hard X-ray emission above
10 keV discovered with INTEGRAL. In this paper we present detailed spectral and temporal …
