Steve Thorsett maintains an interesting pulsar web site.
The Laser Interferometric Gravitational Observatory (LIGO) at Caltech, the interferometer setup planned to study gravitational waves, has a homepage on line. It is a joint project of Caltech and MIT.
Alex Wolszczan writes, as of 1/22/96, that there are still 3 planets around PSR B1257+12 with the indication that there may be a fourth, much more distant one. The distances and masses of the 3 planets are:
Planet Distance Mass Porb AU M(earth) (days) A 0.19 0.015 25.3 B 0.36 3.4 66.5 C 0.47 2.8 98.2
The most recent article on pulsar planets appeared in Science Magazine (Apr 22, 1994 issue). Planets graphics and animation are in his "pulsar" home page.
