Pulsars have been an object of research in several fields notably gravitational waves, the cosmos itself, deep-space navigation, plane localization methods, among others. Pulsar signals have periods ranging from miliseconds to seconds with extremely large period accuracy, comparable to that of atomic clocks.

Space Science Reviews, 1994
25 years after their discovery, pulsars still pose fundamental problems, in particular when the whole range of their periodsP is considered: 1.56 ms ≤P≤0.09 s. This communication reviews my understanding of the pulsar magnetosphere, windzone, and (coherent) radio emission.

Radio Pulsars — What Is to Be Done
Astrophysics and Space Science, 2001In this review the author discusses briefly the main theoretical problems concerning radio pulsars and formulates the observations aimed at a verification of the current models of pulsar magnetosphere and the radio emission mechanism.

Generation of Radio Waves in Pulsars
Nature, 1970Pulsars generate radio waves by an unknown process which gives the highest volume emissivity known in astrophysics. The radiation forms a beam the width and polarization of which are independent of frequency. This article assembles the observational facts which any theory of emission must explain.

The Radio Emission from Pulsars
Reports on Progress in Physics, 1989The basic observed properties of pulsar radio emission are reviewed with a view to guiding their interpretation. Particular attention is given to the location of the sources of emission both in normal and in gamma-ray pulsars, with brief reviews of radio propagation in the magnetosphere and of emission mechanisms.

Radio pulsars were discovered more than 40 years ago and continue to provide fertile scientific research programs. The vast majority of the nearly 2000 pulsars known are detected only at radio wavelengths. Current research at radio wavelengths includes surveys for pulsars, pulsar timing, pulsars as probes of Galactic structure, understanding the ...

AIP Conference Proceedings, 1994
We review the various radio surveys which have been designed primarily for discovering recycled pulsars. In the 11 years since the first millisecond pulsar, PSR 1937+21, was found, a total of about 55 have been discovered, although most of these have only been found since 1988.

Abstract We report the results of our search for pulsed radio emission from Geminga carried out in 1992, 1993 and 1996–1997 at 102.5 MHz using the BSA radiotelescope of the Pushchino Radioastronomy Observatory. The Geminga radio pulsar (PSR J0633+1746) was detected in all three observation periods.

International Astronomical Union Colloquium, 1996
Abstract A review of simultaneous and compiled spectra is presented, and a catalog of radio spectra for 340 pulsars reported. Pulsars with flux density measurements at three and more frequencies are included. Statistics of spectral indices and frequencies of the energy maximum and the break are presented, as well as the correlations with other ...

Astrophysics, 1995
A new version of the theory of pulsar radio emission is developed for the case of a coaxial rotator. It is based on the electric field that we established [G. S. Sahakian, Astrofizika, 37, 97 (1994)] for the radiation channel (the channel of open magnetic field lines) and on convenient approximations for the electron energy obtained in [G. S.
