Abstract:
The discovery of the short-period giant exoplanet population, the
so-called hot Jupiter population, and their link to brown dwarfs and
low-mass stars challenges the conventional view of planet formation
and evolution.
We took advantage of the multi-fiber facilities GIRAFFE and
UVES/FLAMES (VLT) to perform the first large radial velocity survey
using a multi-fiber spectrograph to detect planetary, brown-dwarf
candidates and binary stars.
We observed 816 stars during 5 consecutive half-nights. These stars
were selected within one of the exoplanet fields of the space mission
CoRoT.
Description:
In January 2005 we obtained 5 half-nights in visitor mode with the
FLAMES facilities (program 074.C-0633A) attached to the 8.2m Kueyen
telescope (UT2) based at the ESO-VLT.
