We present relativistic analyses of 9257 measurements of times-of-arrival from the first binary pulsar, PSR B1913+16, acquired over the last 35 years. The determination of the "Keplerian" orbital elements plus two relativistic terms completely characterizes the binary system, aside from an unknown rotation about the line of sight, leading to a determination of the masses of the pulsar and its companion: 1.438 ± 0.001 M ☉ and 1.390 ± 0.001 M ☉, respectively. In addition, the complete system…

PSR J2234+0611: A New Laboratory for Stellar Evolution
We report timing results for PSR J2234+0611, a 3.6-ms pulsar in a 32-day, eccentric (e = 0.13) orbit with a helium white dwarf companion discovered as part of the Arecibo Observatory 327 MHz drift
A Measurement of the Galactic Plane Mass Density from Binary Pulsar Accelerations
We use compiled high-precision pulsar timing measurements to directly measure the Galactic acceleration of binary pulsars relative to the solar system barycenter. Given the vertical accelerations, we

The discovery of the first binary pulsar in 1974 has opened up a completely new field of experimental gravity. In numerous important ways, pulsars have taken precision gravity tests quantitatively
Mass Measurements for Two Binary Pulsars Discovered in the PALFA Survey
In this paper, we present the results of timing observations of PSRs J1949+3106 and J1950+2414, two binary millisecond pulsars discovered in data from the Arecibo ALFA pulsar survey (PALFA). The

The Orbital-decay Test of General Relativity to the 2% Level with 6 yr VLBA Astrometry of the Double Neutron Star PSR J1537+1155
PSR J1537+1155, also known as PSR B1534+12, is the second discovered double neutron star (DNS) binary. More than 20 yr of timing observations of PSR J1537+1155 have offered some of the most precise
Constraints of General Screened Modified Gravities from Comprehensive Analysis of Binary Pulsars
Testing gravity by binary pulsars nowadays becomes a key issue. Screened modified gravity is a kind of scalar-tensor theory with screening mechanism in order to satisfy the tight Solar System tests.
Upgraded Giant Metrewave Radio Telescope timing of NGC 1851A: a possible millisecond pulsar - neutron star system.
1 yr of upgraded Giant Metrewave Radio Telescope timing measurements of PSR J0514-4002A, a 4.99-ms pulsar in a 18.8-d eccentric orbit with a massive companion located in the globular cluster NGC 1851, raise the possibility that the companion is also a neutron star.

Timing Measurements of the Relativistic Binary Pulsar PSR B1913+16
We present results of more than three decades of timing measurements of the first known binary pulsar, PSR B1913+16. Like most other pulsars, its rotational behavior over such long timescales is
Tests of General Relativity from Timing the Double Pulsar
By measuring relativistic corrections to the Keplerian description of the orbital motion, it is found that the “post-Keplerian” parameter s agrees with the value predicted by general relativity within an uncertainty of 0.05%, the most precise test yet obtained.
A new test of general relativity - Gravitational radiation and the binary pulsar PSR 1913+16
Observations of pulse arrival times from the binary pulsar PSR 1913+16 between 1974 September and 1981 March are now sufficient to yield a solution for the component masses and the absolute size of

A detailed account of the parametrized post-Keplerian'' (PPK) formalism, a general phenomenological framework designed to extract the maximum possible information from pulsar timing and pulse-structure data, and how it can be combined with the predictions of a rather generic class of tensor biscalar theories to bring together tests based on observations of several different pulsars.
