  journal={The Astrophysical Journal},
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 of relativistic orbital effects. In others, only an indirect or statistical estimate of the masses is possible. We review the general problem of mass measurement in radio pulsar binaries and critically discuss all current estimates of the masses of radio pulsars and their companions. We find that…

The maximum mass of a neutron star has important implications across multiple research fields, including astrophysics, nuclear physics and gravitational wave astronomy. Compact binary millisecond
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
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
On the Mass Distribution and Birth Masses of Neutron Stars
We investigate the distribution of neutron star masses in different populations of binaries, employing Bayesian statistical techniques. In particular, we explore the differences in neutron star
The two-hour orbit of a binary millisecond X-ray pulsar
Typical radio pulsars are magnetized neutron stars that are born rapidly rotating and slow down as they age on time scales of 10 to 100 million years. In contrast, millisecond radio pulsars spin very
The nature of millisecond pulsars with helium white dwarf companions
We examine the growing data set of binary millisecond pulsars that are thought to have a helium white dwarf companion. These systems are believed to form when a low- to intermediate-mass companion to
Discovery of Two Relativistic Neutron Star-White Dwarf Binaries
We have discovered two recycled pulsars in relativistic orbits as part of the first high-frequency survey of intermediate Galactic latitudes. PSR J1157-5112 is a 44 ms pulsar and the first recycled
We present a systematic study of the evolution of intermediate- and low-mass X-ray binaries consisting of an accreting neutron star of mass 1.0-1.8 M{sub Sun} and a donor star of mass 1.0-6.0 M{sub
Neutron Stars with Submillisecond Periods: A Population of High-Mass Objects?
Rapidly spinning neutron stars, recycled in low-mass binaries, may have accreted a substantial amount of mass. The available relativistic measurements of neutron star masses, all clustering around
Study of measured pulsar masses and their possible conclusions
We study the statistics of 61 measured masses of neutron stars (NSs) in binary pulsar systems, including 18 double NS (DNS) systems, 26 radio pulsars (10 in our Galaxy) with white dwarf (WD)


The Neutron Star-Helium White Dwarf Population in the Galactic Disk
The population of low-mass binary pulsars in the Galactic disk has grown considerably in the past few years. By "low mass," we mean that the companion to the neutron star is, or is very likely to be,
Magnetic Field Decay and the Origin of Neutron Star Binaries
The origin of magnetized neutron stars in binaries and the 1.55 ms pulsar is examined in terms of the magnetic field decay model for radio pulsars with a decay time scale of order 5 x 10 to the 6th
The Masses of the Millisecond Pulsar J1012+5307 and Its White Dwarf Companion
We report on spectroscopy of the white dwarf companion of the millisecond radio pulsar PSR J1012+5307. We find strong Balmer absorption lines, as would be expected for a cool DA white dwarf. The
PSR J0045-7319: A dual-line binary radio pulsar
Binary radio pulsars are superb tools for mapping binary orbits because of the precision of the pulse timing method (e.g., Taylor & Weisberg). To date, all orbital parameters for binary pulsars have
Discovery of a very bright, nearby binary millisecond pulsar
DURING a survey of the southern sky for millisecond pulsars, we have discovered one with by far the greatest flux density of any known millisecond pulsar, often exceeding 1 Jy at 430 MHz. The
Space velocities of radio pulsars from interstellar scintillations
Scintillation observations are used to determine the space velocities of 71 radio pulsars, including most of the 26 objects with proper motions derived from interferometry. The scintillation velocity

Orbital inclination and mass of the binary pulsar PSR0655 + 64
The full determination of the orbits of a binary star system requires measurements of both line-of-sight and transverse velocities. Except for orbits of large angular size, there is usually
