Abstract:
Precise radial-velocity measurements with the HARPS spectrograph
reveal the presence of two planets orbiting the solar-type star HD
45364. The companion masses are Msini=0.187M_{Jup} and 0.658M_{Jup},
with semi-major axes of a=0.681AU and 0.897AU, and eccentricities of
e=0.168 and 0.097, respectively. A dynamical analysis of the system
further shows a 3:2 mean motion resonance between the two planets,
which prevents close encounters and ensures the stability of the
system over 5Gyr. This is the first time that such a resonant
configuration has been observed for extra-solar planets, although
there is an analogue in our Solar System formed by Neptune and Pluto.
This singular planetary system may provide important constraints on
planetary formation and migration scenarios.
