Extrasolar planets and brown dwarfs around A-F type stars. II. A planet found with ELODIE around the F6V star HD 33564

摘要

We present here the detection of a planet orbiting around the F6V star HD33564. The radial velocity measurements, obtained with the ELODIE echellespectrograph at the Haute-Provence Observatory, show a variation with a periodof 388 days. Assuming a primary mass of 1.25 Mo, the best Keplerian fit to thedata leads to a minimum mass of 9.1 MJup for the companion.
