cds-question@unistra.frmultiple-starsf-starssolar-system-planetsradial-velocityIn the frame of the search for extrasolar planets and brown dwarfs around early-type main-sequence stars, we present the detection of a giant planet around the young F-type star HD113337. We estimated the age of the system to be 150^+100^_-50_Myr. Interestingly, an IR excess attributed to a cold debris disk was previously detected on this star. The SOPHIE spectrograph on the 1.93m telescope at the Observatoire de Haute-Provence (OHP) was used to obtain ~300 spectra over 6 years. We used our SAFIR tool, dedicated to the spectra analysis of A and F stars, to derive the radial velocity variations. The data reveal a 324.0^+1.7^_-3.3_days period that we attribute to a giant planet with a minimum mass of 2.83+/-0.24MJup in an eccentric orbit with e=0.46+/-0.04. A long-term quadratic drift, that we assign to be probably of stellar origin, is superimposed to the Keplerian solution.2014A&A...561A..65Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/561/A65CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/491/883 : Radial velocities of HD 60532 (Desort+, 2008)J/A+A/506/1469 : theta Cyg radial velocity variations (Desort+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/561/A65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/561/A65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/561/A65https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/561/A65https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/561/A65http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/561/A65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/561/A65/table2HD 113337 radial velocity measurementsrecnoRecord number assigned by the VizieR team.
