Searching for pulsars in close circular binary systems. Further insights into pulsar kicks from analyses of proper motion and polarization data [ , , ] find strong evidence for an alignment between the spin axis and the velocity vector at birth. Want to know more about travelling around United Kingdom Rome2rio's Travel Guide series provide vital information for the global traveller. URL cited on 19 July Toward an empirical theory of pulsar emission. In addition, if the neutron star progenitor was a member of a binary system prior to the explosion, the pre-supernova orbital velocity will also contribute to the resulting speed of the newly-formed pulsar. This model has gained strong support in recent years from the discoveries of quasi-periodic kHz oscillations in a number of low-mass X-ray binaries [ ], as well as Doppler-shifted 2.

This is consistent, within the uncertainties, of other studies of the millisecond pulsar population [ , ] and with the birth-rate of low-mass X-ray binaries [ , ]. Deep Searches for Young Pulsars.

Cosmological constraints on cosmic-string gravitational radiation. Towards a pulsar virtual observatory. Since the typical ages of millisecond pulsars are several Gyr or more, we expect, from our vantage point in the Galaxy, to be in the middle of an essentially isotropic population of nearby sources. Do neutron stars with kHz spin rates exist? For example, studies of the Parkes multibeam pulsar distribution [ , ] suggest that the NE model underestimates the distances of pulsars close to the Galactic plane. Observing and data analysis systems, discovery and timing of pulsars.
An alternative approach is to undertake a full-blown Monte Carlo simulation of the most likely evolutionary scenarios described in Section 2. Minimal predictions for gravity wave detectors. Principles of Physical Cosmology. The model pulse phase. Binary and millisecond pulsars.
