Rotating Neutron Stars as the Origin of the Pulsating Radio Sources

  title={Rotating Neutron Stars as the Origin of the Pulsating Radio Sources},
  author={Thomas Gold},
The constancy of frequency in the recently discovered pulsed radio sources can be accounted for by the rotation of a neutron star. Because of the strong magnetic fields and high rotation speeds, relativistic velocities will be set up in any plasma in the surrounding magnetosphere, leading to radiation in the pattern of a rotating beacon. 

The Pulsar Magnetosphere and its Role in Beaming Radiation

A simple model is developed for the magnetosphere of a rotating aligned neutron star. It is shown that charged particles can be pulled out of the surface of the star by electric fields of the order

Contribution to the Co-rotating Magnetic Field Model of the Pulsar

A new general solution of the electromagnetic field equations convenient for rotating field problems convenient for low plasma number density is used to analyse the case of low Plasma number density.

Rotating Neutron Stars and Pulsar Emission

The oblique rotator model of a neutron star can provide a mechanism to transfer rotational energy into the circumstellar plasma, producing periodic shock waves. This mechanism is also relevant to the

Rotational Properties of Neutron Star Models

IT has been suggested that pulsars are rotating neutron stars1 and that the energy source of the Crab nebula is the loss of rotational energy from the Crab pulsar2. Because neutron stars are quite

The Nature of Pulsar Radiation

Pulsar radiation may be due to particles which gyrate while moving in bunches along curved orbits and should come from near the speed of light circle; if emitted by protons, they should arise within a few stellar radii of the underlying star.

Magnetic Field Decay in a Neutron Star and the Distribution of Pulsar Periods

HERE I wish to comment briefly on the distribution of pulsar periods in relation to the expected lifetime of the magnetic field in a neutron star.

Spin-down of radio pulsars

Abstract The physical basis for the whole complex of processes proceeding in the pulsar magnetosphere proves to be very simple and natural; all this results from fast rotation in a vacuum of a strong

Scientific Uses of Pulsars

The recently discovered celestial sources of pulsed radio energy can be used to test general relativity, to study the solar corona, and to determine the earth's orbit and ephemeris time. The vector



Observation of a Rapidly Pulsating Radio Source

Unusual signals from pulsating radio sources have been recorded at the Mullard Radio Astronomy Observatory. The radiation seems to come from local objects within the galaxy, and may be associated

Linear Polarization in Pulsating Radio Sources

Signals from all the known radio sources are linearly polarized. The pulses often seem to be made up of separate components showing a high degree of polarization.

Pulse Structure of Four Pulsars

The pulse structure of the four known pulsars is given and the shape of the first subpulse agrees well with the pulse shape expected from a radio-emitting sphere which is excited by a spherically expanding disturbance.

Observations of some further Pulsed Radio Sources

Details are now given of three of the four pulsating radio sources discovered at Cambridge.
