High inclination orbits in the secular quadrupolar three-body problem (2009)

Farago, Francois, Laskar, Jacques

The Lidov-Kozai mechanism allows a body to periodically exchange its eccentricity with inclination. It was first discussed in the framework of the quadrupolar secular restricted three-body problem,...

Speed limit on Neptune migration imposed by Saturn tilting (2009)

Boué, Gwenaël, Laskar, Jacques, Kuchynka, Petr

In this Letter, we give new constraints on planet migration. They were obtained under the assumption that Saturn's current obliquity is due to a capture in resonance with Neptune's ascending node. If...

Mercury's capture into the 3/2 spin-orbit resonance including the effect of core-mantle friction (2009)

Correia, Alexandre C. M., Laskar, Jacques

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 interactions with the Sun...

Erratum: Precession of a planet with a satellite. (2008)

Boué, Gwenaël, Laskar, Jacques

We correct a mistake in the demonstration of the proposition 1, given in section 4 of the paper Icarus, 185 (2006) 312-330 (Paper I). The demonstration is slightly modified but the results remain...

On the equilibrium rotation of Earth-like extra-solar planets (2008)

Correia, Alexandre C. M., Levrard, Benjamin, Laskar, Jacques

The equilibrium rotation of tidally evolved "Earth-like" extra-solar planets is often assumed to be synchronous with their orbital mean motion. The same assumption persisted for Mercury and Venus...

Chaotic diffusion in the Solar System (2008)

Laskar, Jacques

A statistical analysis is performed over more than 1001 different integrations of the secular equations of the Solar system over 5 Gyr. With this secular system, the probability of the eccentricity...

The early Eocene global warming events: Implications from ODP Leg 208 Walvis Ridge depth transect (2007)

Westerhold, Thomas, Röhl, Ursula, Laskar, Jacques, Bowles, Julie, Raffi, Isabella, Lourens, Lucas J, ...

Five sections drilled in multiple holes over a depth transect of more than 2200 m at the Walvis Ridge (SE Atlantic) during Ocean Drilling Program (ODP) Leg 208 resulted in the first complete early...

Tidal dissipation within hot Jupiters: a new appraisal (2007)

Levrard, Benjamin, Correia, Alexandre Morgado, Chabrier, Gilles, Baraffe, Isabelle, Selsis, Franck, Laskar, Jacques

Eccentricity or obliquity tides have been proposed as the missing energy source that may explain the anomalously large radius of some transiting ``hot Jupiters''. To maintain a non-zero and large...

Recent formation and evolution of northern Martian polar layered deposits as inferred from a Global Climate Model (2007)

Levrard, Benjamin, Forget, Francois, Montmessin, Franck, Laskar, Jacques

We present a time-marching model which simulates the exchange of water ice between the Martian northern cap, the tropics and a high-latitude surface reservoir. Net annual exchange rates of water and...

Note on the generalized Hansen and Laplace coefficients (2004)

The rotation of extra-solar planets (2004)

Laskar, Jacques, Correia, Alexandre

Although observations of the rotations rates of the extra-solar planets will probably not be obtained soon, one can make predictions for these rates for all planets that should have tidally evolved,...

A long term numerical solution for the insolation quantities of the Earth (2004)

Laskar, Jacques, Robutel, Philippe, Joutel, Frédéric, Gastineau, Mickael, Correia, Alexandre C.M., Levrard, Benjamin

We present here a new solution for the astronomical computation of the insolation quantities on Earth spanning from -250 Myr to 250 Myr. This solution has been improved with respect to La93 (Laskar...
