PSR B1257+12 and the first confirmed planets beyond the solar system

Research output: Chapter in Book/Report/Conference proceedingChapter


We describe the survey and timing observations conducted in early 1990 with the Arecibo radio telescope, which have led to the discovery of the first confirmed extrasolar planetary system consisting of three low-mass planets, orbiting the 6.2-ms millisecond pulsar, PSR B1257+12. The existence of planets around a neutron star has carried with it a now fulfilled promise that planets should be common around the various types of stars. Furthermore, the architecture of the PSR B1257+12 system offered an early preview of the future discoveries of the very common compact systems of superEarth-mass planets by the Kepler telescope and ground-based radial velocity surveys.
