Pulse Astronomy: Short Time Scale Phenomena in Electromagnetic and Gravitational Wave Astronomy, scales. The motions of planets in our solar system take place on a time scale of the order of years or decades; in double star systems, the orbital periods range from days to millennia. Likewise, changes in the properties of individual astronomical bodies generally take place on extremely long time

Observational Properties of Pulsars,een learned of their properties. Pulsars are slowly rotating (~1 Hz) neutron stars with huge magnetic fields (~10. G) which convert rotational energy into energy of (radio) radiation and relativistic particles. The pulsed radiation presumably arises from a beaming effect associated with the magnetic

Optical Observations of Binary X-Ray Sources,efly, and without much notice, with optical telescopes long before they were known to be sources of high-energy photons. These earlier observations gave no indication of the special properties which compel us at this time to consider the possiblity that systems of this class contain such bizarre obj

Black Holes and Neutron Stars: Evolution of Binary Systems,r radiates electromagnetic energy nor energy in the form of gravitational radiation (Zel’dovich and Novikov, 1967, 1971). Thus, detection of such an object is limited to the influence of its static gravitational field, or to the electromagnetic radiation of gas undergoing accretion or acceleration i
