Binary and Millisecond Pulsars [PDF]
Annual Review of Astronomy and Astrophysics, 1994 Most of the ~600 known pulsars are single and located in the disk of our Galaxy. There is circumstantial evidence that the pulsars in this majority are created in supernova (SN) explosions, by the collapse of the cores of massive stars (initial mass M_i ≳ M_(cr) ≃ 8 M_⊙). One is created roughly every 100 y in the Galaxy.

Nature, 1977
As X-ray astronomy enters the Einstein era when faint, distant, and exotic X-ray sources are being investigated, we thought it might be useful to review some of the progress made over the past decade on a class of relatively nearby objects that have contributed richly to our understanding of astrophysics — the binary X-ray pulsars.

A Millisecond Pulsar in an Eclipsing Binary
Nature, 1988We report the discovery of a remarkable pulsar with period 1.6 ms, moving in a nearly circular 9.17 hour orbit around a low mass companion star. At an observing frequency of 430 MHz, the pulsar, PSR 1957+20, is eclipsed once each orbit for about 50 minutes.

Relativistic gravity and binary radio pulsars [PDF]
Eighth Canadian conference on general relativity and relativistic astrophysics, 1999 Following a summary of the basic principles of pulsar timing, we present a review of recent results from timing observations of relativistic binary pulsars. In particular, we summarize the status of timing observations of the much celebrated original binary pulsar PSR B1913+16, draw attention to the recent confirmation of strong evidence for geodetic ...

The binary and millisecond pulsars
Contemporary Physics, 1992Abstract Most of the 500 known pulsars are solitary. A recently discovered population of binary pulsars now amounts to about 3% of the total; most of these have very short periods, and many of them are found in Globular Clusters. There is a clear evolutionary link between the X-ray binaries and pulsars. Mass transfer within the binary provides both the
