Information on the properties and distributions of the charges responsible for pulsar emission can be deduced from an appraisal of the coherent synchrotron radiation from an oblique rotator model. 

Low Mode Coherent Synchrotron Radiation and Pulsar Models

The radio pulses from pulsars are considered to be formed from the beamed radiation from relativistic electrons. This radiation is in low order harmonics of the gyro frequency, giving pulse shapes

Polarization of Pulsar Radiation

The polarization of radiation from four pulsars has been measured and interpretations of the results are suggested.

Pulsar Sub-pulses and the Emission Process

This article describes another regular phenomenon in the sub-pulse behaviour of pulsars that follows a sawtooth pattern with a linearly increasing drift speed and sudden jumps as the speed drops to repeat the cycle.

Beams and Cones from Aligned Rotators

Curvature radiation from corotating relativistic particles in filled magnetospheric shells has been postulated as the source of coherent radio pulsar emission from oblique rotators. With the addition

On the Origin of Pulsar Radiation

The pulsar theory involves three main questions: 1) type and constitution of the central body (of the star); 2) structure of the magnetosphere; 3) mechanisms of radio emission from pulsars. A

Theory of pulsar magnetospheres

There is a wide range of fundamental physical problems directly related to how pulsars function. Some of these are independent of the specific pulsar mechanism. Others relate directly to the physics

The nature of radio emission from pulsars

It is shown that radio emission from pulsars is unlikely to be of coherent synchrotron origin if the surface magnetic field of the central neutron star is greater than 108 G.



Oblique Rotator and Pulsar Radiation

Stars with a dipole magnetic field oriented at an angle to the rotation axis may emit pulsating radio signals.

Further Observations of Pulsating Radio Sources at 13 cm

This article describes a series of measurements of the pulsating radio CP 0834, CP 0950, CP 1133 and CP 1919.

Polarization of Radio Pulses from Pulsar CP 0328

Pulse by pulse observations of CP 0328 have revealed very high degrees of polarization.

Relativistic Beaming of Radiation from Pulsars

THE observation that the pulsar CP 0328 radiates single pulses which seem to be basic elements of the total radio radiation, and which are highly polarized1, led at first to the suggestion that the

Observations of Pulsar NP 0527

SINCE December 20, 1968, we have observed a pulsar in the vicinity of the Crab Nebula with the longest period yet reported for any pulsar. Measurements have been made with the 1,000 foot diameter

Frequency Dependent Pulse Widths for CP 1133

MEASUREMENTS of average pulse shape made at the Arecibo Ionospheric Observatory have shown that the duration of an average pulse from the pulsar CP 1133 increases progressively with decreasing radio

Some Difficulties with the Oblique Rotator Model for Pulsars

PRACTICALLY all the available evidence up to now (short duration of pulses, rapid pulsing, slowing down of the period, association with past supernovae, and so on) suggests that pulsars are produced

Magnetic Dipole Radiation from Pulsars

RADIO astronomers1–3 have recently discovered pulsars in Vela and near the Crab nebula which seem to be associated with supernova remnants and have repetition periods (0.0892 s and 0.0331 s)

Population II Star Models and Abundance of Primaeval Helium

SINCE the discovery of the 3° K cosmic blackbody radiation1, the hypothesis of helium formation in a primordial fireball has received some support. Peebles2 and Wagoner, Fowler and Hoyle3 have
