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 with oscillations of white dwarf or neutron stars. 

Possible Model for a Rapidly Pulsating Radio Source

The pulsating radio signals may come from active regions on rapidly rotating white dwarf stars. This accounts for some aspects of the periodicity of the signals which are difficult to explain if the

Rapidly Pulsing Radio Sources

The gravitational lens effect associated with a neutron star binary gives results which agree well with recent observations of a new class of rapidly pulsing radio sources. Further tests of the

New Pulsating Radio Source

Harvard radio astronomers have discovered a new pulsating radio source with a pulse repetition period of 0.73968 ± 0.00002 s.

Pulsed Radio Sources

The bursts of radio waves at decametric wavelengths emitted by Jupiter suggest a model for producing the signals from the pulsating radio sources. This mechanism includes polarization of the signals

Measurement of the Interstellar Magnetic Field

The discovery that signals from pulsating radio sources are linearly polarized means that interstellar magnetic fields in the local part of the Galaxy can be measured.

Pulsars: Observations of Spectra

Dynamic spectrograms of two of the recently discovered pulsating radio sources have been obtained. The data provide the instantaneous spectrum and the time-frequency history of the signals over a

Measurements of the Pulse Shape and Spectra of the Pulsating Radio Sources

Simultaneous measurements of the pulsating radio signals at several frequencies have been made with the 250 ft. telescope at Jodrell Bank. Some of the pulses are double, suggesting two separated

Search for Optical Flashes from the Radio Source CP 1919

THE four rapidly pulsating radio sources discovered by Hewish et al.1 have been tentatively identified with neutron stars or white dwarfs, and their optical identification is therefore of great

Pulsating Radio Source at α = 19h19m, δ = +22°

Signals from one of the rapidly pulsating radio sources have been recorded on three frequencies using the mark I radio telescope at the Nuffield Radio Astronomy Laboratories. The size of the source,

Radio Pulse Profiles from Pulsating White Dwarfs

Radii and relative rotation rates have been deduced for the four known pulsating radio sources. Most of the emission appears to come from a wide belt near latitude 20° in each hemisphere, a



Possible Magnetospheric Phenomena associated with Neutron Stars

WITH the discovery of X-ray sources in the sky1,2, speculation has arisen that they might be associated with neutron or hyperon stars formed during the internal collapse which triggers off supernova
