Beginning of ReadMe : J/A+A/388/632 Radial-velocity of HD 108147 and HD 168746 (Pepe+, 2002) ================================================================================ The CORALIE survey for southern extra-solar planets. VII. Two short-period Saturnian companions to HD 108147 and HD 168746. Pepe F., Mayor M., Galland F., Naef D., Queloz D., Santos N.C., Udry S., Burnet M. <Astron. Astrophys. 388, 632 (2002)> =2002A&A...388..632P (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Radial velocities Keywords: techniques: radial velocities - stars: individual: HD 108147 - stars: individual: HD 168746 - stars: planetary systems Abstract: We present the discovery of two Saturn-mass companions to HD 108147 and HD 168746. Both belong to the lightest ever discovered planets. The minimum mass of the companion to HD 168746 is of only 0.77 the mass of Saturn and its orbital period is 6.4 days. The companion to HD 108147 orbits its parent star in 10.9 days and its minimum mass is 1.34 that of Saturn. Its orbit is characterized by a high eccentricity, e=0.50, indicating possibly the presence of a second companion. The detection of Saturn-mass planets by means of the Doppler technique demands high radial-velocity measurement precision. The two new candidates were discovered by means of the CORALIE echelle spectrograph. The instrumental accuracy of CORALIE combined with the simultaneous ThAr-reference technique has reached a level better than 3m/s. On many observed objects the precision is now limited by photon noise. Description: Precise radial-velocity data of HD 108147 and HD 168746 taken with the CORALIE instrument on the Leonard-Euler Swiss 1.2m Telescope at the ESO La Silla Observatory. Julian date, radial velocity and error are given.
