The incidence of evaporating `black widow' pulsars (BWPs) among all millisecond pulsars is far higher in globular clusters than in the field. This implies a special formation mechanism for them in clusters. Cluster millisecond pulsars in wide binaries with white dwarf companions exchange them for turnoff-mass stars. These new companions eventually overflow their Roche lobes because of encounters and tides. The millisecond pulsars eject the overflowing gas from the binary, giving mass loss on… Expand

The population of black widow pulsars
We consider the population of black widow pulsars (BWPs). The large majority of these are members of globular clusters. For minimum companion masses 0.1 M⊙ are systems relaxing to equilibrium after aExpand
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. Expand
Origin and binary evolution of millisecond pulsars
We summarize the channels formation of neutron stars (NS) in single or binary evolution and the classic recycling scenario by which mass accretion by a donor companion accelerates old NS toExpand
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.

Inferring the composition of super-Jupiter mass companions of pulsars with radio line spectroscopy
We propose using radio line spectroscopy to detect molecular absorption lines (such as OH at 1.6-1.7 GHz) before and after the total eclipse of black widow (BW) and other short orbital period binaryExpand
The magnetic fields of millisecond pulsars in globular clusters
Many of the characteristic properties of the millisecond pulsars found in globular clusters are markedly different from those in the Galactic disc. We find that one such physical parameter is theExpand
Halo millisecond pulsars ejected by intermediate-mass black holes in globular clusters
Intermediate-mass black holes (IMBHs) are among the most elusive objects in contemporary astrophysics. Both theoretical and observational evidence of their existence are subject of debate.Expand
Magnetic-driven Orbital Evolution of an Accreting Millisecond Pulsar: Witnessing the Banquet of a Hidden Black Widow
We report here on the orbital evolution of the accreting millisecond pulsar SAX J1808.4{3658. In particular, we nd for this source the rst estimate of the orbital period derivative in an accretingExpand
Radio Timing and Optical Photometry of the Black Widow System PSR J1953+1846A in the Globular Cluster M71
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. By using the accurateExpand
Properties and Evolution of the Redback Millisecond Pulsar Binary PSR J2129-0429
PSR J2129-0429 is a "redback" eclipsing millisecond pulsar binary with an unusually long 15.2 hour orbit. It was discovered by the Green Bank Telescope in a targeted search of unidentified FermiExpand


Fate of the companion stars of ultra-rapid pulsars
A millisecond pulsar that is formed by spin-up 'recycling'1,2 in a binary system will, once the mass transfer becomes temporarily interrupted, start to evaporate its companion star as a consequenceExpand
Formation of Short-Period Binary Pulsars in Globular Clusters.
A new dynamical scenario for the formation of short-period binary millisecond pulsars in globular clusters driven by a combination of gravitational radiation and tidal heating of the companion. Expand
On the origin of the eclipsing pulsar PSR B1718-19 and its wind
The recent discovery of PSR B1718-19 in NGC 6342, the first globular-cluster pulsar with a high magnetic field and the third eclipsing pulsar (Lyne et al. 1993) may lead to an unambiguous test ofExpand
Neutron star retention and millisecond pulsar production in globular clusters
We investigate the conditions by which neutron star retention in globular clusters is favoured. We find that neutron stars formed in massive binaries are far more likely to be retained. Such binariesExpand
An eclipsing millisecond pulsar in the globular cluster Terzan 5

Where May Ultrafast Rotating Neutron Stars Be Hidden
The existence of ultrafast rotating neutron stars (spin period P 1 ms) is expected on the basis of current models for the secular evolution of interacting binaries, although they have not beenExpand
