Here we report timing measurements of the relativistic binary PSR J1141-6545 that constrain the component masses and demonstrate that the orbital period derivative b = (-4 ± 1) × 10-13 is consistent with gravitational wave emission as described by the general theory of relativity. The mass of the neutron star and its companion are 1.30 ± 0.02 and 0.986 ± 0.02 M☉, respectively, suggesting a white dwarf companion and extending the range of systems for which general relativity provides a correct…

Heavy Neutron Stars? A Status Report on Arecibo Timing of Four Pulsar-White Dwarf Systems
Relativistic phenomena (orbital precession, Shapiro delay, and/or orbital decay) have been measured in Arecibo timing observations of four pulsar-white dwarf binaries, leading to constraints on the
A 2.1 M☉ Pulsar Measured by Relativistic Orbital Decay
PSR J0751+1807 is a millisecond pulsar in a circular 6 hr binary system with a helium white dwarf secondary. Through high-precision pulse timing measurements with the Arecibo and Effelsberg radio
Gravitational-radiation losses from the pulsar-white-dwarf binary PSR J1141-6545
Pulsars in close binary systems with white dwarfs or other neutron stars make ideal laboratories for testing the predictions of gravitational radiation and self-gravitational effects. We report new
Merger of white dwarf-neutron star binaries: Prelude to hydrodynamic simulations in general relativity
White dwarf-neutron star binaries generate detectable gravitational radiation. We construct Newtonian equilibrium models of corotational white dwarf-neutron star (WDNS) binaries in circular orbit and
Equation of state constraints from neutron stars
Abstract Recent measurements of thermal radiation from neutron stars have suggested a rather broad range of radiation radii ( $R_{\infty}=R/\sqrt{1-2GM/Rc^{2}}\,$ ). Sources in M13 and Omega Cen
The Physics of Neutron Stars
Observations that include studies of pulsars in binary systems, thermal emission from isolated neutron stars, glitches from pulsars, and quasi-periodic oscillations from accreting neutron stars provide information about neutron star masses, radii, temperatures, ages, and internal compositions.
Pulsars in Binary Systems: Probing Binary Stellar Evolution and General Relativity
Radio pulsars in binary orbits often have short millisecond spin periods as a result of mass transfer from their companion stars, which provide constraints on binary evolution, characteristics of the binary pulsar population, and the masses of neutron stars with different mass-transfer histories.
A Double-Pulsar System: A Rare Laboratory for Relativistic Gravity and Plasma Physics
The detection of the 2.8-second pulsar J0737–3039B as the companion to the 23-millisecond pulsars in a highly relativistic double neutron star system, allowing unprecedented tests of fundamental gravitational physics.
The estimations of neutron star mass and radius by the kHz QPOs
The kHz quasi-periodic oscillations (QPOs) have been detected by the RXTE satellite in about thirty neutron stars (NSs) in low mass X-ray binaries (LMXBs), which are usually interpreted to be related


A neutral hydrogen distance limit to the relativistic binary PSR J1141-6545
We have obtained an HI absorption spectrum of the relativistic binary PSR J1141-6545 and used it to constrain the distance to the system. The spectrum suggests that the pulsar is at, or beyond, the
A test of general relativity from the three-dimensional orbital geometry of a binary pulsar
High-precision radio observations of the binary millisecond pulsar PSR J0437-4715 are reported, which establish the three-dimensional structure of its orbit and see the Shapiro delay predicted by general relativity, and the mass of the neutron star and its white dwarf companion is determined.

Discovery of a Young Radio Pulsar in a Relativistic Binary Orbit
We report on the discovery of PSR J1141-6545, a radio pulsar in an eccentric, relativistic 5 hr binary orbit. The pulsar shows no evidence of being recycled, having a pulse period P = 394 ms, a

Neutron Star Mass Measurements. I. Radio Pulsars
There are now about 50 known radio pulsars in binary systems, including at least five in double neutron star binaries. In some cases, the stellar masses can be directly determined from measurements

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.
A New method for obtaining binary pulsar distances and its implications for tests of General Relativity
We demonstrate how measuring orbital period derivatives can lead to more accurate distance estimates and transverse velocities for some nearby binary pulsars. In many cases this method will estimate

By considering the evolution of intermediate mass binary systems with periods similar to the Be X-ray binaries we find that if a kick velocity of a few hundred kilometres per second is imparted to

A generic class of theories where gravity is mediated by one tensor field together with an arbitrary number of scalar fields is considered. The predictions of these theories are worked out in four
