We have discovered a 716-hertz eclipsing binary radio pulsar in the globular cluster Terzan 5 using the Green Bank Telescope. It is the fastest spinning neutron star found to date, breaking the 24-year record held by the 642-hertz pulsar B1937+21. The difficulty in detecting this pulsar, because of its very low flux density and high eclipse fraction (∼40% of the orbit), suggests that even faster spinning neutron stars exist. If the pulsar has a mass less than twice the mass of the Sun, then its… 

Accretion powered X-ray millisecond pulsars

Neutron Stars are among the most exotic objects in the Universe. A neutron star, with a mass of 1.4-2 Solar masses within a radius of about 10-15 km, is the most compact stable configuration of

LOFAR Discovery of the Fastest-spinning Millisecond Pulsar in the Galactic Field

We report the discovery of PSR J0952−0607, a 707 Hz binary millisecond pulsar that is now the fastest-spinning neutron star known in the Galactic field (i.e., outside of a globular cluster). PSR

Does Submillisecond Pulsar XTE J1739−285 Contain a Weak Magnetic Neutron Star or Quark Star?

The possible detection of the fastest spinning nuclear‐powered pulsar XTE J1739−285, of frequency 1122 Hz (0.8913 ms), arouses us to constrain the mass and radius of its central compact object and to

Extreme Spinning Tops

Observations of the same binary star system over 10 years confirm a scenario of how pulsars form and evolve, and provide evidence in support of a long-suspected evolutionary scenario in the formation of such extreme objects.

Spin-Down of Radio Millisecond Pulsars at Genesis

Binary stellar evolution calculations are reported that show that the braking torque acting on a neutron star, when the companion star decouples from its Roche lobe, is able to dissipate >50% of the rotational energy of the pulsar.

Binary and Millisecond Pulsars

The main properties, demographics and applications of binary and millisecond radio pulsars are reviewed.

The Role of Binary Pulsars in Testing Gravity Theories

Radio pulsars are neutron stars (NSs) which emit collimated beams of radio waves, observed as pulses, once per rotation of the NS. A subgroup of the radio pulsars behave as highly stable clocks and

N ov 2 00 8 Binary and Millisecond Pulsars

We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to

The Double Pulsar

A new eaa in fundamental physics began with the discovery of pulsars 1967, the discovery of the first binary pulsar in 1974 and the first millisecond pulsar in 1982. Ever since, pulsars have been

Binary Millisecond Pulsar Discovery via Gamma-Ray Pulsations

A computing-intensive blind search of gamma-ray data from the Fermi Large Area Telescope detected a 2.5-millisecond pulsar, PSR J1311−3430, which unambiguously explains a formerly unidentified Gamma-ray source that had been a decade-long enigma, confirming previous conjectures.



Radio pulsars in Terzan 5

We report on searches of the globular cluster Terzan 5 for low-luminosity and accelerated radio pulsars using the 64-m Parkes radio telescope. One new millisecond pulsar, designated PSR J1748−2446C,

A new class of radio pulsars

Sufficiently low magnetic field neutron stars which accrete for long times from a surrounding keplerian disk can be spun up to millisecond periods. After accretion ceases, such stars could become

Gravitational Radiation and Rotation of Accreting Neutron Stars

Recent discoveries by the Rossi X-Ray Timing Explorer indicate that most of the rapidly accreting (Ṁ ≳ 10−11 M yr−1) weakly magnetic (B≪1011 G) neutron stars in the Galaxy are rotating at spin

A millisecond pulsar

The puzzle of the radio properties of 4C21.53 may be resolved by the discovery and related observations of a fast pulsar, 1937+214, with a period of 1.558 ms in the constellation Vulpecula only a few degrees from the direction to the original pulsar.

Nuclear-powered millisecond pulsars and the maximum spin frequency of neutron stars

Millisecond pulsars are neutron stars that are thought to have been spun-up by mass accretion from a stellar companion. It is not known whether there is a natural brake for this process, or if it

An Eclipsing Millisecond Pulsar with a Possible Main-Sequence Companion in NGC 6397

We present the results of 1 yr of pulse timing observations of PSR J1740-5340, an eclipsing millisecond pulsar located in the globular cluster NGC 6397. We have obtained detailed orbital parameters

Twenty-One Millisecond Pulsars in Terzan 5 Using the Green Bank Telescope

Thirteen of the new MSPs are in binaries, of which two show eclipses and two have highly eccentric orbits, indicating that at least one of these pulsars has a mass 1.68 times greater than the mass of the Sun at 95% confidence.

An eclipsing millisecond pulsar in the globular cluster Terzan 5

WE HAVE discovered an eclipsing binary millisecond pulsar in the globular cluster Terzan 5. This, the second known eclipsing binary pulsar after PSR1957 + 20, has a pulse period of 11.56 ms and a

Gravitational Radiation Limit on the Spin of Young Neutron Stars

A newly discovered instability in rotating neutron stars, driven by gravitational radiation reaction acting on the stars' r-modes, is shown here to set an upper limit on the spin rate of young

Green Bank Telescope Discovery of Two Binary Millisecond Pulsars in the Globular Cluster M30

We report the discovery of two binary millisecond pulsars in the core-collapsed globular cluster M30 using the Green Bank Telescope (GBT) at 20 cm. PSR J2140-2310A (M30A) is an eclipsing 11 ms pulsar
