Abstract:
Since 1998, a planet-search around main sequence stars within 50pc in
the southern hemisphere has been underway with the CORALIE
spectrograph at La Silla Observatory.
With an observing time span of more than 20 years, the CORALIE survey
is able to detect long-term trends in data with masses and separations
large enough to select ideal targets for direct imaging. Detecting
these giant companion candidates will allow us to start bridging the
gap between radial-velocity-detected exoplanets and directly imaged
planets and brown dwarfs.
Long-term precise Doppler measurements with the CORALIE spectrograph
reveal radial-velocity signatures of massive planetary companions and
brown dwarfs on long-period orbits.
In this paper we report the discovery of new companions orbiting
HD 181234, HD 13724, HD 25015, HD 92987 and HD 50499. We also report
updated orbital parameters for HD 50499b, HD 92788b and HD 98649b. In
addition, we confirm the recent detection of HD 92788c. The newly
reported companions span a period range of 15.6 to 40.4 years and a
mass domain of 2.93 to 26.77 MJup, the latter of which straddles the
nominal boundary between planets and brown dwarfs.
We report the detection of five new companions and updated parameters
of four known extrasolar planets. We identify at least some of these
companions to be promising candidates for imaging and further
characterisation.
Description:
Radial velocity measurements for HD181234, HD25015, HD50499, HD92788,
HD98649, HD13724, HD92987. In addition, H-alpha time series data for
HD25015, with the date of the measurement in Julian days [JD], the
H-alpha index and the error on the H-alpha index. Each file has the
date of the measurement in Julian days [JD], the radial velocity
measurement in m/s and the error on the radial velocity measurement.
