Query: The ELODIE survey for northern extra-solar planets IV. HD196885, a close
  binary star with a 3.7-year planet   Aims:We aim to significantly increase the number of detected extra-solar
planets in a magnitude-limited sample to improve our knowledge of their orbital
element distributions and thus obtain better constraints for planet-formation
models.
  Methods: Radial-velocity data were taken at Haute-Provence Observatory (OHP,
France) with the ELODIE echelle spectrograph.
  Results: We report the presence of a planet orbiting HD 196885 A, with an
orbital period of 1349 days. This star was previously suggested to host a 386
-day planet, but we cannot confirm its existence. We also detect the presence
of a stellar companion, HD 196885 B, and give some constraints on its orbit.
