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.

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.

The discovery of the binary pulsar
Reviews of Modern Physics, 1994Exactly 20 years ago today, on December 8, 1973, I was at the Arecibo Observatory in Puerto Rico recording in my notebook the confirming observation of the first pulsar discovered by the search which formed the basis for my Ph.D. thesis. As excited as I am sure I was at that point in time, I certainly had no idea of what lay in store for me in the ...

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

Relativistic Shapiro delay measurements of an extremely massive millisecond pulsar
Nature Astronomy, 2019Despite its importance to our understanding of physics at supranuclear densities, the equation of state (EoS) of matter deep within neutron stars remains poorly understood. Millisecond pulsars (MSPs) are among the most useful astrophysical objects in the

Binary and Millisecond Pulsars
2014The first evidence for neutron stars residing in binaries came in the early 60s when Giacconi et al. (1962) discovered the first extrasolar X-ray source, Sco X\(-\)1.

Interstellar scintillations of binary pulsars
AIP Conference Proceedings, 1988We have measured interstellar scintillations of two binary pulsars (1855+09 and 1913+16) to determine their transverse velocities at numerous points in their orbits. Combining transverse velocities with radial velocities derived from Doppler shifts, one can (in principle) determine a binary system’s proper motion and orbital inclination, and the bulk ...

11 Millisecond and binary pulsars
2012A distinct population The millisecond pulsars are in a different category from the general population of ‘normal’ pulsars. The majority of pulsars are following a simple course of evolution, from a birth in a supernova, through a slowdown from a rotational period at birth of some tens of milliseconds to a death at around one second when the radiation

Navigation using binary pulsars
Science China Physics, Mechanics and Astronomy, 2012The issue of navigation using binary pulsars is investigated in this paper. We show how the effect of the binary motion is incorporated in the navigation measurement equation. Necessary reference systems and time scales are introduced and the transformation between different time scales is derived. Based mainly on Damour and Deruelle’s binary model and
