Pulsar Planet?

Andrew Lyne and Matthew Bailes thought that they had made a remarkable discovery in 1991, when they reported that they had discovered a pulsar orbited by a planetary companion; this would have been the first planet detected around another star. However, after this was announced, the group went back and checked their work, and found that they had not properly removed the effects of the Earth's motion around the Sun from their analysis, and, when the calculations were redone correctly, the pulse variations that led to their conclusions disappeared, and that there was in fact no planet around PSR 1829-10. When Lyne announced the retraction of his results at a meeting of the American Astronomical Society, he received a standing ovation from his scientific colleagues for having the intellectual integrity and the courage to admit this error publicly.

In popular culture

The American band Neutrino wrote and recorded a song named for Lyne, and included it on their 1998 album Improved Hearing Through Amplification.

Double Pulsar

No retraction was necessary in 2003, when Lyne and his team discovered J0737-3039 the first binary system found in which both components were pulsed neutron stars. Lyne's colleague Richard Manchester called the PSR J0737-3039 system a "fantastic natural laboratory" for studying specialized effects of the General Theory of Relativity. Other recent work that Prof. Lyne has undertaken includes research on the globular cluster at 47 Tucanae, whose dense stellar population acts as a nursery for millisecond and binary pulsars.
