Abstract:
We report the detection of three new extrasolar planets orbiting the
solar type stars HD 85390, HD 90156 and HD 103197 with the HARPS
spectrograph mounted on the ESO 3.6-m telescope at La Silla
observatory. HD 85390 has a planetary companion with a projected
intermediate mass (42.0Mearth) on a 788-day orbit (a=1.52AU) with an
eccentricity of 0.41, for which there is no analogue in the solar
system. A drift in the data indicates the presence of another
companion on a long period orbit, which is however not covered by our
measurements. HD 90156 is orbited by a warm Neptune analogue with a
minimum mass of 17.98Mearth (1.05Mneptune), a period of 49.8 days
(a=0.25AU) and an eccentricity of 0.31. HD 103197 has an intermediate
mass planet on a circular orbit (P=47.8d, Msini=31.2Mearth). We
discuss the formation of planets of intermediate mass (30-100Mearth)
which should be rare inside a few AU according to core accretion
formation models.
