A New Search Technique for Short Orbital Period Binary Pulsars

  title={A New Search Technique for Short Orbital Period Binary Pulsars},
  author={Scott M. Ransom and James M. Cordes and Stephen S. Eikenberry},
  journal={The Astrophysical Journal},
We describe a new and efficient technique, which we call sideband or phase-modulation searching, that allows one to detect short-period binary pulsars in observations longer than the orbital period. The orbital motion of the pulsar during long observations effectively modulates the phase of the pulsar signal, causing sidebands to appear around the pulsar spin frequency and its harmonics in the Fourier transform. For the majority of binary radio pulsars or low-mass X-ray binaries (LMXBs), large… Expand

How to detect the shortest period binary pulsars in the era ofLISA
We discuss a multimessenger strategy to detect radio pulses from Galactic binary neutron stars in a very tight orbit with the period shorter than 10 min. On one hand, all-sky surveys by radioExpand

An RXTE archival search for coherent X-ray pulsations in the low-mass X-ray binary 4U 1820-30
As part of a large-scale search for coherent pulsations from low-mass X-ray binaries (LMXBs) in the Rossi X-Ray Timing Explorer (RXTE) archive, we have completed a detailed series of searches forExpand
Impact of the orbital uncertainties on the timing of pulsars in binary systems
The detection of pulsations from an X-ray binary is an unambiguous signature of the presence of a neutron star in the system. When the pulsations are missed in the radio band, their detection atExpand
A Fourier Domain “Jerk” Search for Binary Pulsars
While binary pulsar systems are fantastic laboratories for a wide array of astrophysics, they are particularly difficult to detect. The orbital motion of the pulsar changes its apparent spinExpand
