On the velocity distribution of radio pulsars at birth
We investigate the transverse velocity distribution of young (< 3 Myr) radio pulsars, using pulsar population synthesis techniques. We find that, after taking into account errors in proper motion measurements, an initial velocity distribution that has many more pulsars at low velocities than the distribution proposed by Lyne & Lorimer (1994) can produce a transverse velocity distribution that d...
متن کاملThe Velocity Distribution of Isolated Radio Pulsars
We infer the velocity distribution of radio pulsars based on large-scale 0.4 GHz pulsar surveys. We do so by modelling evolution of the locations, velocities, spins, and radio luminosities of pulsars; calculating pulsed flux according to a beaming model and random orientation angles of spin and beam; applying selection effects of pulsar surveys; and comparing model distributions of measurable p...
متن کاملA note on solid pulsars
After a brief introduction to the necessary of quark stars in modelling pulsars, I present a qualitative analysis of the solidification of quark matter with low-temperature but high-density. The reason, that a solid neutron star could not be possible, is also given. Subject headings: pulsars: general — stars: neutron — elementary particles What’s the nature of pulsars? This question seems to ha...

We explore a simple model for the representation of the observed distributions of the motions, and the characteristic ages of the local population of pulsars. The principal difference from earlier models is the introduction of a unique value, S, for the kick velocity with which pulsars are born. We consider separately the proper motion components in galactic longitude and latitude, and find tha...

In the framework of linear transformations between inertial systems, there are no physical reasons for assuming any anisotropy in the one-way velocity of light. Pacs 03.30 Special relativity
