In 1996, a team of astronomers (including Eric Williams, Heather M. Hauser, and Phil Shirts) led by Geoffrey W. Marcy and R. Paul Butler announced the discovery of a Jupiter -
class planet around Star A using highly sensitive radial - velocity methods (Butler et al, 1997).

Previous observations of other hot Jupiter -
