Abstract:
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.
Radial-velocity data were taken at Haute-Provence Observatory (OHP,
France) with the ELODIE echelle spectrograph.
We report the presence of a planet orbiting HD 196885A, 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 196885B, and give some
constraints on its orbit.
