Andrew Lyne

Andrew G. Lyne FRS (born 1942) is a British physicist. Lyne is Langworthy Professor of Physics in the School of Physics and Astronomy, University of Manchester, as well as an ex-director of the Jodrell Bank Observatory and leader of its [http://www.jb.man.ac.uk/~pulsar/ Pulsar Group] .

Professor Lyne was educated at The Portsmouth Grammar School, and the University of Cambridge (natural sciences), continuing to the University of Manchester for a PhD in Radio Astronomy.

Lyne writes on his homepage at [http://www.jb.man.ac.uk/~agl/ http://www.jb.man.ac.uk/~agl] that he is "mostly interested in finding and understanding radio pulsars in all their various forms and with their various companions. Presently, I am most occupied with the development of new multibeam search systems at Jodrell and Parkes, in order to probe deeper into the Galaxy, particularly for millisecond pulsars, young pulsars and any that might be in binary systems."

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; [http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1991Natur.352..311B] 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.

Binary Pulsar

No retraction was necessary in 2003, when Lyne and his team discovered [http://arxiv.org/abs/astro-ph/0401086 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 Dr. Lyne has undertaken includes research on the globular cluster at [http://www2.naic.edu/~pfreire/47Tuc/#New_Paper 47 Tucanae] , whose dense stellar population acts as a nursery for millisecond and binary pulsars.

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.
