Abstract:
In 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+100-50Myr. 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+1.7-3.3days 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.
Description:
266 radial velocity measurements of HD113337 are presented. For each
measurement the date of the observation, radial velocity, uncertainty
on the radial velocity are given, plus a flag corresponding to the
removing of an instrumental effect on the SOPHIE spectrograph.
