Long-term evolution of the spin of Mercury I. Effect of the obliquity and core-mantle friction
A. C. M. Correia, J. Laskar
The present obliquity of Mercury is very low (less than 0.1 degree), which led previous studies to always adopt a nearly zero obliquity during the planet's past evolution. However,…

HD45364, a pair of planets in a 3:2 mean motion resonance
A. C. M. Correia, S. Udry, M. Mayor +8
Precise radial-velocity measurements with the HARPS spectrograph reveal the presence of two planets orbiting the solar-type star HD45364. The companion masses are 0.187 Mjup and 0.…

Mercury's capture into the 3/2 spin-orbit resonance including the effect of core-mantle friction
Alexandre C. M. Correia, Jacques Laskar
The rotation of Mercury is presently captured in a 3/2 spin-orbit resonance with the orbital mean motion. The capture mechanism is well understood as the result of tidal interactio…
