Beginning of ReadMe : J/A+A/523/A88 A Jupiter-mass companion around HD 109246 (Boisse+, 2010) ================================================================================ The SOPHIE search for northern extrasolar planets. III. A Jupiter-mass companion around HD 109246. Boisse, I., Eggenberger, A., Santos, N.C., Lovis C., Bouchy F., Hebrard G., Arnold L., Bonfils X., Delfosse X., Desort M., Diaz R.F., Ehrenreich D., Forveille T., Gallenne A., Lagrange A.M., Moutou C., Udry S., Pepe F., Perrier C., Perruchot S., Pont F., Queloz D., Santerne A., Segransan D., Vidal-Madjar A. <Astron. Astrophys. 523, A88 (2010)> =2010A&A...523A..88B ================================================================================ ADC_Keywords: Stars, dwarfs ; Stars, S ; Planets ; Radial velocities ; Spectroscopy Keywords: planetary systems - techniques: radial velocities - stars: individual: HD 109246 - stars: activity - stars: abundances Abstract: We report the detection of a Jupiter-mass planet discovered with the SOPHIE spectrograph mounted on the 1.93-m telescope at the Haute-Provence Observatory. The new planet orbits HD 109246, a G0V star slightly more metallic than the Sun. HD 109246b has a minimum mass of 0.77M_jup_, an orbital period of 68 days, and an eccentricity of 0.12. It is placed in a sparsely populated region of the period distribution of extrasolar planets. We also present a correction method for the so-called seeing effect that affects the SOPHIE radial velocities. We complement this discovery announcement with a description of some calibrations that are implemented in the SOPHIE automatic reduction pipeline. These calibrations allow the derivation of the photon-noise radial velocity uncertainty and some useful stellar properties (vsini, [Fe/H], log R'hk) directly from the SOPHIE data. Description: Radial velocity measurements of HD 109246 obtained with the SOPHIE spectrograph and stars used to calibrate the Ssophie into the SMount Wilson to measure the logR'hk from the SOPHIE spectra.
