The double pulsar: evolutionary constraints from the system geometry
R. D. Ferdman, I. H. Stairs, M. Kramer +6
The double pulsar system PSR J0737-3039A/B is a highly relativistic double neutron star (DNS) binary, with a 2.4-hour orbital period. The low mass of the second-formed NS, as well…
A 610-MHz Galactic Plane Pulsar Search with the Giant Meterwave Radio Telescope
B. C. Joshi, M. A. McLaughlin, M. Kramer +5
We report on the discovery of three new pulsars in the first blind survey of the north Galactic plane (45 < l < 135 ; |b| < 1) with the Giant Meterwave Radio telescope (GMRT) at an…
Discovery of Pulsations and a Possible Spectral Feature in the X-ray Emission from Rotating Radio Transient J1819-1458
M. A. McLaughlin, N. Rea, B. M. Gaensler +7
PSR J1819-1458 is a rotating radio transient (RRAT) source with an inferred surface dipole magnetic field strength of 5e13 G and a 4.26-s spin period. We present XMM-Newton observa…
A characteristic observable signature of preferred frame effects in relativistic binary pulsars
N. Wex, M. Kramer
In this paper we develop a consistent, phenomenological methodology to measure preferred-frame effects (PFEs) in binary pulsars that exhibit a high rate of periastron advance. We s…
Age constraints in the double pulsar system J0737-3039
D. R. Lorimer, P. C. C. Freire, I. H. Stairs +10
We investigate the age constraints that can be placed on the double pulsar system using models for the spin-down of the first-born 22.7-ms pulsar A and the 2.77-s pulsar B with cha…
LOFAR: A powerful tool for pulsar studies
B. W. Stappers, A. G. J. van Leeuwen, M. Kramer +2
The LOw Frequency ARray, LOFAR, will have the sensitivity, bandwidth, frequency range and processing power to revolutionise low-frequency pulsar studies. We present results of simu…
