This paper summarizes the information gathered for 16 still
unpublished exoplanet candidates discovered with the CORALIE echelle
spectrograph mounted on the Euler Swiss telescope at La Silla
Observatory. Amongst these new candidates, 10 are typical extrasolar
Jupiter-like planets on intermediate- or long-period
(100 < P ≤ 1350 d) and fairly eccentric
(0.2 ≤ e ≤ 0.5) orbits (HD 19994, HD 65216,
HD 92788, HD 111232, HD 114386, HD 142415, HD 147513,
HD 196050, HD 216437, HD 216770). Two of these stars are in
binary systems. The next 3 candidates are shorter-period planets
(HD 6434, HD 121504) with lower eccentricities among which we find
a hot Jupiter (HD 83443). More interesting cases are given by the
multiple-planet systems HD 82943 and HD 169830. The former is a
resonant 
= 2/1 system in which planet-planet
interactions are influencing the system evolution. The latter is
more hierarchically structured.
Key words: techniques: radial velocities / techniques: spectroscopic – stars: activity – stars: planetary systems
Based on observations collected with the CORALIE echelle spectrograph on the 1.2-m Euler Swiss telescope at La Silla Observatory, ESO Chile.
The precise radial velocities presented in this paper are available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/415/391, except for the multi-planet systems that will appear in a future paper describing their dynamical evolutions, taking planet-planet interaction into account.
