Algorithmic Pulsar Timer for Binaries
The Astrophysical JournalPulsar 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 ...

The Confrontation between General Relativity and Experiment
Living Reviews in Relativity, 2014 The status of experimental tests of general relativity and of theoretical frameworks for analyzing them is reviewed and updated. Einstein’s equivalence principle (EEP) is well supported by experiments such as the Eötvös experiment, tests of local Lorentz

The Origin of the Binary Pulsar J0737-3039 [PDF]
Physical Review Letters, 2005 Evolutionary scenarios suggest that the progenitor of the new binary pulsar J0737-3039B \cite{ref1,ref2} was a He-star with $M > 2.1-2.3~\Ms$ \cite{ref3,ref4}. We show that this case implies that the binary must have a large ($>120$ km/s) center of mass velocity.

New binary pulsar constraints on Einstein-æther theory after GW170817 [PDF]
Classical and quantum gravity, 2021 The timing of millisecond pulsars has long been used as an exquisitely precise tool for testing the building blocks of general relativity, including the strong equivalence principle and Lorentz symmetry.

A highly magnetized environment in a pulsar binary system [PDF]
Nature, 2022 The observation of pulsar emission at various orbital phases of a companion star probes the diverse magnetic structure in a binary system, and exhibits varying polarization behavior, akin to that observed in certain fast radio bursts.

Lense–Thirring frame dragging induced by a fast-rotating white dwarf in a binary pulsar system [PDF]
Science, 2020 Pulsar timing detects frame dragging Frame dragging is a predicted phenomenon in general relativity, whereby a rotating mass drags the surrounding spacetime around with it. Venkatraman Krishnan et al.

Radio Timing and Optical Photometry of the Black Widow System PSR J1953+1846A in the Globular Cluster M71 [PDF]
, 2015 We report on the determination of the astrometric, spin and orbital parameters for PSR J1953+1846A, a "black widow" binary millisecond pulsar in the globular cluster M71.

Binary and Millisecond Pulsars [PDF]
Annual Review of Astronomy and Astrophysics, 1994 Most of the ~600 known pulsars are single and located in the disk of our Galaxy. There is circumstantial evidence that the pulsars in this majority are created in supernova (SN) explosions, by the collapse of the cores of massive stars (initial mass M_i ≳ M_(cr) ≃ 8 M_⊙). One is created roughly every 100 y in the Galaxy.
