Pulsars show intensity variations over timescales ranging from a few microseconds to a few years. Short-term intensity variations, i.e. those having timescales of a few minutes to a few hours had Cited by: 2.   Submillisecond Radio Intensity Variations in Pulsars. Abstract. Two pulsars have been observed with a time resolution of ms using the 1, ft radio telescope at Arecibo, revealing structure showing circular polarization within the by: The effects of this may be thought of either as refraction or as diffraction; in more general terms the waves are scattered, giving rise to an angular spread of waves and to subsequent fluctuations in wave amplitude, which are seen as intensity variations Author: Andrew Lyne, Francis Graham-Smith.   Observations at J odrell Bank of the intensity variations from ten pulsars are described. Two regimes are established. A pulse-to-pulse fluctuation is imposed at the source, simultaneously Cited by:

  Frequency Structure of Pulsar Intensity Variations. Abstract. THIS communication reports that a programme of observations at Jodrell Bank on ten pulsars has shown that the long term fading of pulse intensities Cited by: Simultaneous observations at MHz of the intensity variations of seven pulsars have been conducted over a km baseline between Australia and India. The Sounds of Pulsars. A pulsar is a highly magnetised neutron star, with a radius of km, having somewhat greater mass than the Sun which has a radius of approximately 1 million km. Radiation is . In some cases, however, the origin of the long-term variation is still not clear. On , A flux variation event in the nearby pulsar PSR B+74 (period s, dispersion measure ) over Cited by: 3.

ADS Classic is now deprecated. It will be completely retired in October This page will automatically redirect to the new ADS interface at that point. New measurements of the slow amplitude variations of the Crab pulsar at MHz are presented. Both the rms depth of variation and the typical time-scale confirm the interpretation that the variability Cited by: Pulsar Properties For additional information about pulsars, see the books P ulsar Astronomy by Andrew Lyne and Francis Graham-Smith and H andbook of Pulsar Astronomy by Duncan Lorimer and Michael Kramer. Known radio pulsars . Known radio pulsars appear to emit short pulses of radio radiation with pulse periods between ms and seconds. Even though the word pulsar is a combination of "pulse" and "star," pulsars are .
