PLANETS AROUND PULSARS COME AND GO . Just as Alexander Wolszcan of Cornell was announcing the discovery of planets around the pulsar PSR 1257+12, Andrew G. Lyne of the University of Manchester was retracting his claim (made in July 1991) for a planet around pulsar PSR 1829-10. Lyne said, at last week's meeting of the American Astronomical Society in Atlanta, that the modulation of radio waves coming from PSR 1829-10 was caused not by the presence of a planet but was in fact an artifact of the Earth's motion around the Sun, a possibility that had been considered but then discounted in earlier studies of the data. "Our embarrassment is unbounded," Lyne had to admit to a sympathetic audience at the AAS meeting.
