Pulsar electrodynamics has been built up by taking ingredients from two models, the vacuum-dipole model, which ignores the magnetosphere but includes the inductive electric field due to the obliquely ...
Assessing the Role of Spin Noise in the Precision Timing of Millisecond Pulsars
the Role of Spin Noise the Precision Timing

We investigate rotational spin noise (referred to as timing noise) in non-accreting pulsars: millisecond pulsars, canonical pulsars, and magnetars. Particular attention is placed on quantifying the st...

Thanks to the recent discovery by Fermi of about fifty new gamma-ray pulsars, it becomes possible to look for statistical properties of their pulsed high-energy emis-sion, especially their light-curve...

Millisecond x-ray pulsars have weak magnetic dipole moments of ∼ 1016 Tm3 compared to ordinaryX-ray pulsars with dipolemoments of 1020 Tm3. For this reason a surrounding accretion
disc can exte...
