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.

Binary X-Ray Pulsars

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, 1988
We 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.
