On the nature and evolution of the unique binary pulsar J1903+0327
P. C. C. Freire, C. G. Bassa, N. Wex +16
(abridged) PSR J1903+0327, a millisecond pulsar in an eccentric (e = 0.44) 95-day orbit with a (~ 1Msun) companion poses a challenge to our understanding of stellar evolution in bi…
A white dwarf companion to the relativistic pulsar PSR J1141-6545
J. Antoniadis, C. G. Bassa, N. Wex +2
Pulsars with compact companions in close eccentric orbits are unique laboratories for testing general relativity and alternative theories of gravity. Moreover, they are excellent t…
Detecting massive gravitons using pulsar timing arrays
Kejia Lee, Fredrick A. Jenet, Richard H. Price +2
Massive gravitons are features of some alternatives to general relativity. This has motivated experiments and observations that, so far, have been consistent with the zero mass gra…
The orthometric parameterisation of the Shapiro delay and an improved test of general relativity with binary pulsars
Paulo C. C. Freire, Norbert Wex
(abridged) In this paper, we express the relativistic propagational delay of light in the space-time of a binary system (commonly known as the "Shapiro delay") as a sum of harmonic…
The Deceptively Boring PSR J1738+0333
Paulo Freire, Norbert Wex
We present preliminary results of 7 years of Arecibo timing of the pulsar-white dwarf binary PSR J1738+0333. We can measure the proper motion, parallax with excellent precision and…
Generic Gravity Tests with the Double Pulsar
N. Wex, M. Kramer
Presently the double pulsar allows for the measurement of six post-Keplerian parameters. In addition, its double-line nature gives access to the projected semi-major axes of both o…
