We report the detection of two very eccentric planets orbiting HD4113 and
HD156846 with the CORALIE Echelle spectrograph mounted on the 1.2-m Euler Swiss
telescope at La Silla. The first planet, HD4113b, has minimum mass of
msini=1.6±0.2MJup, 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=1.28
AU which displays an additional radial velocity drift of 28 m s−1/yr
observed during 8 years. The combination of the radial-velocity data and the
non-detection of any main sequence stellar companion in our high contrast
images taken at the VLT with NACO/SDI, characterizes the companion as a
probable brown dwarf or as a faint white dwarf. The second planet, \object{HD
156846 b}, has minimum mass of msini=10.45±0.05 MJup, a period
of P=359.51±0.09 days, an eccentricity of e=0.847±0.002 and is located
at a=1.0 AU from its parent star. HD156846 is a metal rich G0 dwarf and is
also the primary of a wide binary system (a>250 AU, P>4000 years). Its
stellar companion, \object{IDS 17147-1914 B}, is a M4 dwarf. The very high
eccentricities of both planets can be explained by Kozai oscillations induced
by the presence of a third object.Comment: 4 pages, 5 figures, A&A Letter accepte
