Searching for pulsars in close circular binary systems [PDF]

, 2002
We present a detailed mathematical analysis of the Fourier response of binary pulsar signals whose frequencies are modulated by circular orbital motion. The fluctuation power spectrum of such signals is found to be νorb-periodic over a compact frequency ...

First Systematic Study Reporting the Changes in Eclipse Cutoff Frequency for Pulsar J1544+4937

The Astrophysical Journal
We present results from long-term monitoring of frequency-dependent eclipses of the radio emission from PSR J1544+4937, which is a black widow spider millisecond pulsar (MSP) in a compact binary system.

Verification of f(R)-gravity in binary pulsars

EPJ Web of Conferences, 2016
We develop the parameterized post-Keplerian approach for class of analytic f (R)-gravity models. Using the double binary pulsar system PSR J0737-3039 data we obtain restrictions on the parameters of this class of f (R)-models and show that f (R)-gravity ...

Binary Pulsars: Observations and Implications [PDF]

Symposium - International Astronomical Union, 1987
The Galaxy contains a large number of neutron stars in gravitation-ally bound binary systems. Among the most fruitful of these to study have been the binary radio pulsars, of which seven are now known. Unlike the “accretion-powered” neutron stars located in mass-exchanging X-ray binary systems, the “rotation-powered” binary radio pulsars are found in ...

The ms pulsar - low mass X-ray binary link [PDF]

, 2016
The recent discovery of a binary millisecond pulsar in the globular cluster M28 that switched between an X-ray pulsar and a radio pulsar state demonstrated the tight link shared by millisecond pulsars and their accreting low-mass X-ray binary progenitors.

Populating the Galaxy with pulsars - I. Stellar and binary evolution

, 2008
The computation of theoretical pulsar populations has been a major component of pulsar studies since the 1970s.However, the majority of pulsar population synthesis has only regarded isolated pulsar evolution.

Algorithmic Pulsar Timer for Binaries

The Astrophysical Journal
Pulsar timing is a powerful tool that, by accounting for every rotation of a pulsar, precisely measures the spin frequency, spin frequency derivatives, astrometric position, binary parameters when applicable, properties of the interstellar medium, and ...

Search for binary milli-second pulsars in unidentified Fermi sources [PDF]

, 2016
We report on the preliminary results of a pilot project of multi-wavelength observations of candidate milli-second pulsars associated with unidentified gamma -ray sources detected by Fermi, carried out with both ground and space-based observatories, and ...
