Kinematics of Radio Pulsars
A very good fraction of stars in the sky are believed to be in binary (or multiple) systems. Therefore, we expect a good fraction of pulsars to have originated in binary systems. However, observations of pulsars have shown that most of the pulsars are not in binary system now. This would imply that these pulsars must have become solitary after the disruption of their progenitor binary system du...
متن کاملEnergetic Young Radio Pulsars
Young radio pulsars shed vast amounts of rotational energy, sometimes as high as 100,000 times the total energy loss rate from the sun. The wide range of phenomena resulting from this energy loss include: glitches, timing noise, jets, bow shocks, bullets and plerions and are be reviewed from an observational perspective. Past and proposed surveys for young radio pulsars are summarised along wit...
متن کاملJets from Radio Pulsars
The observational evidence for jets and phenomena arising from rotation powered radio pulsars is reviewed, including many recent and exciting discoveries at X-ray wavelengths. The well studied jets of the Crab pulsar are summarised, including recent results from the HST. The evolutionary links between the known binary radio pulsars and jets sources in X-ray binaries are discussed.
متن کاملOn the absence of mildly recycled radio pulsars amongst the population of ordinary single radio pulsars
Current scenarios for the evolution of binaries predict that only 1%or less of the single radio pulsars in the galactic disk have been recycled in a binary. The fraction of such pulsars amongst the detected single radio pulsars is smaller than this. For magnetic field strengths B > 1012 G the period vs. magnetic field diagram shows no evidence for injection of pulsars at P ∼ 0.5 s. For magnetic...
متن کاملEmission altitude in radio pulsars
This paper presents a method of estimation of emission altitudes using observational data-precise measurements of pulse profile widths at low intensity level. The analysis of emission altitudes obtained using this method for a large number of pulsars gives constraints that should be useful for theory of coherent pulsar emission. It seems that radio emission originates at altitudes of about few ...
