Gregory Henry of Tennessee State University, Nashville, and his team are reporting in The Astrophysical Journal, 577:L111-L114, 2002 October 1 that at least one of the 100 or so planets discovered around other stars is an impostor. Astronomers claimed in 1999 that shifts in the frequency of light from the star HD 192263 were due to the pull of a large planet. But a paper to be published in the 1 October issue of Astrophysical Journal Letters finds that the light varies on a regular cycle. attribute this to the rotation of large 'star-spots', cooler regions associated with magnetic activity, on the star's surface. Only stars with active surfaces exhibit this behavious, so only a few planets of the 100 may be bogus.
