Abstract:
We report the detection of two very eccentric planets orbiting HD 4113
and HD 156846 with the CORALIE Echelle spectrograph mounted on the
1.2-m Euler Swiss telescope at La Silla.
The first planet, HD 4113 b, has minimum mass of
msini=1.6±0.2M{Jup}, a period of P=526.59±0.21-days and an
eccentricity of e=0.903±0.02. It orbits a metal rich G5V star at
a=1.28AU, which displays an additional radial velocity drift of 28m/s/
observed during 8 years.
The second planet, HD 156846 b, has minimum mass of
msini=10.45±0.05M{Jup}, a period of P=359.51±0.09days, an
eccentricity of e=0.847±0.002 and is located at a=1.0AU from its
parent star. HD 156846 is a metal rich G0 dwarf and is also the
primary of a wide binary system (a>250AU, P>4000-years). Its stellar
companion, IDS 17147-1914 B, is a M4 dwarf.
Description:
We present here radial-velocity measurements for two solar type stars:
HD 4113 and HD156846. These radial velocities were obtained using the
CORALIE echelle spectrograph mounted on the 1.2-m Euler Swiss
telescope at the ESO-La Silla Observatory (Chile).

Note (1): The CORALIE Echelle spectrograph was upgraded in July 2007 which
affected the instrument zero point. We decided to refer to the
original CORALIE as CORALIE-98 and to the upgraded one as CORALIE-07.
When using both set of data, the instrumental zero point should be
adjusted.
Note (2): Instrument used as follows:
C98 = CORALIE-98
C07 = CORALIE-07
