The path to instability in compact multi-planetary systems
Antoine C. Petit, Gabriele Pichierri, Melvyn B. Davies +1
The dynamical stability of tightly packed exoplanetary systems remains poorly understood. While for a two-planet system a sharp stability boundary exists, numerical simulations of…
The onset of instability in resonant chains
Gabriele Pichierri, Alessandro Morbidelli
There is evidence that most chains of mean motion resonances of type : among exoplanets become unstable once the dissipative action from the gas is removed from the system,…
The role of dissipative evolution for three-planet, near-resonant extrasolar systems
Gabriele Pichierri, Konstantin Batygin, Alessandro Morbidelli
Early dynamical evolution of close-in planetary systems is shaped by an intricate combination of planetary gravitational interactions, orbital migration, and dissipative effects. W…
Capture into first-order resonances and long-term stability of pairs of equal-mass planets
Gabriele Pichierri, Alessandro Morbidelli, Aurélien Crida
Massive planets form within the lifetime of protoplanetary disks and undergo orbital migration due to planet-disk interactions. When the first planet reaches the inner edge of the…
Extreme Secular Excitation of Eccentricity Inside Mean Motion Resonance: Driving Small Bodies into Star-Grazing Orbits by Planetary Perturbations
Gabriele Pichierri, Alessandro Morbidelli, Dong Lai
It is well known that asteroids and comets fall into the Sun. Metal pollution of white dwarfs and transient spectroscopic signatures of young stars like -Pic provide growing evi…
