Abstract:
The vast diversity of planetary systems detected to date is defying
our capability of understanding their formation and evolution.
Well-defined volume-limited surveys are the best tool at our disposal
to tackle the problem, via the acquisition of robust statistics of the
orbital elements. We are using the HARPS spectrograph to conduct our
survey of 850 nearby solar-type stars, and in the course of the past
nine years we have monitored the radial velocity of HD 103774,
HD 109271, and BD-061339. In this work we present the detection of
five planets orbiting these stars, with msini between 0.6 and 7
Neptune masses, four of which are in two multiple systems, comprising
one super-Earth and one planet within the habitable zone of a
late-type dwarf. Although for strategic reasons we chose efficiency
over precision in this survey, we have the capability to detect
planets down to the Neptune and super-Earth mass range as well as
multiple systems, provided that enough data points are made available.
