We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly... In the absence of constraints from the binary companion or supernova remnant, the standard method for estimating pulsar ages is to infer an age from the rate of spin-down. While the generic spin-down age may give realistic estimates for normal pulsars, it can fail for pulsars with very short periods ... This tutorial lecture outlines the essentials of making and analyzing timing observations of binary and millisecond pulsars. Many of the necessary procedures are, of course, similar to those used for slow, single pulsars. However, achieving the best attainable timing accuracy for millisecond pulsars requires much tighter tolerances on observing and data-processing procedures, and the presence ... Further applications became possible with the discovery of the first binary pulsar in 1974 and the discovery of millisecond pulsars in 1982. Ever since pulsars have been used as precise cosmic clocks, taking us beyond the weak-field limit of the solar-system in the study of theories of gravity. Their contribution is crucial as no test can be considered to be complete without probing the strong ... We performed a drift-scan pulsar survey using the Green Bank Telescope (GBT) in West Virginia, USA. The survey is among the most sensitive ever undertaken in the Northern sky, and was collected with the Berkeley-Caltech Pulsar Machine filterbank. It was performed at low frequencies (400, 600, and 800 MHz) and mostly high Galactic latitudes with the aim of detecting new binary and millisecond ... We report our multi-band infrared (IR) imaging of the transitional millisecond pulsar system J1023+0038, a rare pulsar binary known to have an accretion disk in 2000-2001. The observations were carried out with ground-based and space telescopes from near-IR to far-IR wavelengths. We detected the source in near-IR JH bands and Spitzer 3.6 and 4.5 {mu}m mid-IR channels. Combined with the ... A list of provisional parameters for the 11 binary and 15 millisecond (spin period <30 ms) pulsar discoveries are shown in Table 2. All but two of the binary discoveries are also millisecond pulsars. Listed for comparison are the spectral S/N for both the standard and stack acceleration searches and the S/N from the candidate plot. For solitary and long orbital period binaries, the S/N for the ... We present time-resolved optical spectroscopy of the ‘redback’ binary millisecond pulsar system PSR J1023+0038 during both its radio pulsar (2009) and accretion disc states (2014 and 2016). We provide observational evidence for the companion star being heated during the disc state. We observe a spectral type change along the orbit, from ∼G5 to ∼F6 at the secondary star’s superior and ... Abstract. Irradiation‐induced companion winds and a new model for the evaporation of the companion of the millisecond pulsar B1957+20 are discussed. The model may account for all companionless mill... Millisecond radio pulsars are often located in binary systems3. In a widely accepted theoretical model4,5, they started as ordinary pulsars which lost most of their magnetic field and were ‘spun ...

Scott Ransom wins the American Astronomical Society's 2010 Helen B. Warner Prize! In this video, he explains what a millisecond pulsar is. Animation of the 2016 discovery of Einstein's Gravity Wave... Predicted by Einstein 100 years ago, this animation shows two orbiting Millisecond Pulsars ejecting energy in the form of Gravity ... It pairs a 1.7-millisecond pulsar named PSR J1023+0038 -- J1023 for short -- with a star containing about one-fifth the mass of the sun. The stars complete an orbit in only 4.8 hours, which places ... Exoplanet Exploration Planets Beyond Solar System - Life on Earth and in the Universe Documentary Space & The Universe HD 1,209 watching Live now Millisecond pulsars are neutron stars that attain their very quick rotation during a Gyr long, X-ray bright phase of accretion of matter from a low mass companion star.

While scientists expect the complete evolution of a low-mass X-ray binary into a millisecond pulsar should happen over several billion years, there is a period of time when the system can switch ... This beautiful globular cluster harbours 22 millisecond pulsars with periods between 2 and 8 ms. Many of them have a binary companion. We can estimate that hundreds more of these objects are in ...
