Effective resonant stability of Mercury
M. Sansottera, C. Lhotka, A. Lemaître
Mercury is the unique known planet that is situated in a 3:2 spin-orbit resonance nowadays. Observations and models converge to the same conclusion: the planet is presently deeply…
On the relativistic Lagrange-Laplace secular dynamics for extrasolar systems
M. Sansottera, L. Grassi, A. Giorgilli
We study the secular dynamics of extrasolar planetary systems by extending the Lagrange-Laplace theory to high order and by including the relativistic effects. We investigate the l…
Effective stability around the Cassini state in the spin-orbit problem
Marco Sansottera, Christoph Lhotka, Anne Lemaître
We investigate the long-time stability in the neighborhood of the Cassini state in the conservative spin-orbit problem. Starting with an expansion of the Hamiltonian in the canonic…
