- 1 January 1992
MILLISECOND radio pulsars, which are old (∼109yr), rapidly rotating neutron stars believed to be spun up by accretion of matter from their stellar companions, are usually found in binary systems with…
The Characteristics of Millisecond Pulsar Emission. I. Spectra, Pulse Shapes, and the Beaming Fraction

The extreme physical conditions in millisecond pulsar magnetospheres, as well as an evolutionary history that differs from that of normal pulsars, raise the question whether these objects also differ…
Confirmation of Earth-Mass Planets Orbiting the Millisecond Pulsar PSR B1257 + 12

- 22 April 1994
The unambiguous detection of this effect, after 3 years of systematic timing observations of PSR B1257+12 with the 305-meter Arecibo radiotelescope, constitutes irrefutable evidence that the first planetary system around a star other than the sun has been identified.
A nearby 37.9-ms radio pulsar in a relativistic binary system

- 1 April 1991
WITH very few exceptions1, high Galactic latitudes have not been surveyed with sufficient sensitivity to detect millisecond pulsars. Accordingly we have conducted a preliminary sensitive survey at…
A Massive Neutron Star in the Globular Cluster M5

- 26 December 2007
We report the results of 19 years of Arecibo timing for two pulsars in the globular cluster NGC 5904 (M5), PSR B1516+02A (M5A) and PSR B1516+02B (M5B). This has resulted in the measurement of the…
Discovery of two radio pulsars in the globular cluster M15

- PhysicsNature
- 5 July 1990
WE report the discovery of two radio pulsars, 2127 + 11B and 2127-11C, in the globular cluster M15 (NGC7078), which also contains the 110-ms pulsar 2127 + 11A (ref. 1). Although only twenty globular…
Masses and Orbital Inclinations of Planets in the PSR B1257+12 System
- M. Konacki, A. Wolszczan
- Physics, Geology
- 28 May 2003
We present measurements of the true masses and orbital inclinations of the two Earth-mass planets in the PSR B1257+12 system, based on the analysis of their mutual gravitational perturbations…
The Proper Motion, Age, and Initial Spin Period of PSR J0538+2817 in S147
- M. Kramer, A. Lyne, A. Wolszczan
- Physics
- 30 June 2003
We present results of the timing observations of the 143 ms pulsar PSR J0538+2817 that provide a proper-motion measurement clearly showing an association of the pulsar with the supernova remnant…
Studies of the Relativistic Binary Pulsar PSR B1534+12. I. Timing Analysis
- I. Stairs, S. Thorsett, J. Taylor, A. Wolszczan
- Physics
- 19 August 2002
We have continued our long-term study of the double neutron star binary pulsar PSR B1534+12, using new instrumentation to make very high precision measurements at the Arecibo Observatory. We have…
