Beginning of ReadMe : J/A+A/447/1159 Radial velocities of HD 142022 (Eggenberger+, 2006) ================================================================================ The CORALIE survey for southern extrasolar planets. XIV. HD 142022 b: a long-period planetary companion in a wide binary. Eggenberger A., Mayor M., Naef D., Pepe F., Queloz D., Santos N.C., Udry S., Lovis C. <Astron. Astrophys., 447, 1159-1163 (2006)> =2006A&A...447.1159E ================================================================================ ADC_Keywords: Radial velocities ; Stars, double and multiple ; Planets Keywords: techniques: radial velocities - stars: individual: HD 142022 - stars: binaries: visual - stars: planetary systems Abstract: We report precise Doppler measurements of HD 142022 obtained during the past six years with the CORALIE echelle spectrograph at La Silla Observatory together with a few additional observations made recently with the HARPS echelle spectrograph. Our radial velocities reveal evidence of a planetary companion with an orbital period P=1928^+53^_-39^d, an eccentricity e=0.53^+0.23^_-0.18_, and a velocity semiamplitude K=92^+102^_-29_m/s. The inferred companion minimum mass is M_2_sini=5.1^+2.6^_-1.5_M_Jup_ and the semimajor axis a=3.03+/-0.05AU. Only one full orbital revolution has been monitored yet, and the periastron passage could not be observed since the star was too low on the horizon. The eccentricity and velocity semiamplitude remain therefore quite uncertain and the orbital solution is preliminary. HD 142022 is a chromospherically inactive K0 dwarf, metal rich relative to the Sun, and is the primary component of a wide binary. HD 142022b is thus a new "planet in binary" candidate, and its high eccentricity might be due to secular interactions with the distant stellar companion. Description: Table 3 gives the 70 radial-velocity measurements of HD 142022 obtained with the CORALIE spectrograph together with the 6 radial-velocity measurements obtained with the HARPS spectrograph. The CORALIE spectrograph is mounted on the Swiss telescope at the ESO La Silla Observatory. The HARPS spectrograph is mounted on the ESO 3.6-m telescope at the ESO La Silla Observatory. Each instrument has its own velocity zero point. A velocity offset of -8.8m/s must be added to the HARPS measurements to convert them into the CORALIE velocity system.
