SXP 1062, a young Be X-ray binary pulsar with long spin period - implications for the neutron star birth spin [PDF]

, 2011
Context. The Small Magellanic Cloud (SMC) is ideally suited to investigating the recent star formation history from X-ray source population studies. It harbours a large number of Be/X-ray binaries (Be stars with an accreting neutron star as companion ...

Supernova remnant S147 and its associated neutron star(s)

, 2005
The supernova remnant S147 harbors the pulsar PSR J0538+2817 whose characteristic age is more than an order of magnitude greater than the kinematic age of the system (inferred from the angular offset of the pulsar from the geometric center of the ...

Probing Pulsar Winds Using Inverse Compton Scattering [PDF]

, 1999
We investigate the effects of inverse Compton scattering by electrons and positrons in the unshocked winds of rotationally-powered binary pulsars. This process can scatter low energy target photons to produce gamma rays with energies from MeV to TeV. The

GAMMA-RAY SIGNAL FROM THE PULSAR WIND IN THE BINARY PULSAR SYSTEM PSR B1259−63/LS 2883 [PDF]

, 2011
Binary pulsar systems emit potentially detectable components of gamma-ray emission due to Comptonization of the optical radiation of the companion star by relativistic electrons of the pulsar wind, both before and after termination of the wind.

Radio pulsar binaries in globular clusters: their orbital eccentricities and stellar interactions

, 2009
High sensitivity searches of globular clusters (GC) for radio pulsars by improved pulsar search algorithms and sustained pulsar timing observations have so far yielded some 140 pulsars in more than two dozen GCs.

A Lower Mass Estimate for PSR J0348+0432 Based on CHIME/Pulsar Precision Timing

The Astrophysical Journal Letters
The binary pulsar J0348+0432 was previously shown to have a mass of approximately 2 M _⊙ , based on the combination of radial-velocity and model-dependent mass parameters derived from high-resolution optical spectroscopy of its white-dwarf companion.
