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,…

CoRoT-2a magnetic activity: hints for possible star-planet interaction

Isabella Pagano, Antonino F. Lanza, Giuseppe Leto +3

CoRoT-2a is a young (about 0.5 Gyr) G7V star accompanied by a transiting hot-Jupiter, discovered by the CoRoT satellite (Alonso et al. 2008; Bouchy et al. 2008). An analysis of its…

Is Beta Pic b the transiting planet of November 1981?

A. Lecavelier des Etangs, A. Vidal-Madjar

In 1981, Beta Pictoris showed strong and rapid photometric variations that were attributed to the transit of a giant comet or a planet orbiting at several AUs (Lecavelier des Etang…

The origin of hydrogen around HD 209458b

A. Lecavelier des Etangs, A. Vidal-Madjar, J. -M. Desert

Using numerical simulation, Holmstrom et al. (2008) proposed a plausible alternative explanation of the observed Lyman-alpha absorption that was seen during the transit of HD 20945…

Radial velocity follow-up for confirmation and characterization of transiting exoplanets

F. Bouchy, C. Moutou, D. Queloz +1

Radial Velocity follow-up is essential to establish or exclude the planetary nature of a transiting companion as well as to accurately determine its mass. Here we present some elem…

On the protection of extrasolar Earth-like planets around K/M stars against galactic cosmic rays

J. -M. Grießmeier, A. Stadelmann, J. L. Grenfell +2

Previous studies have shown that extrasolar Earth-like planets in close-in habitable zones around M-stars are weakly protected against galactic cosmic rays (GCRs), leading to a str…

HD60532, a planetary system in a 3:1 mean motion resonance

J. Laskar, A. C. M. Correia

In a recent paper it was reported a planetary system around the star HD60532, composed by two giant planets in a possible 3:1 mean motion resonance, that should be confirmed within…

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…
