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,…
