The emergence of orbital resonances among planets is a natural consequence of the early
dynamical evolution of planetary systems. While it is well established that convergent …

In this work, we investigate configuration formation of two inner terrestrial planets near mean
motion resonance (MMR) induced by the perturbation of a distant gas giant for the Kepler-68 …

We investigate a repulsion mechanism between two low-mass planets migrating in a
protoplanetary disk, for which the relative migration switches from convergent to divergent …

We develop a code to compute different chaos indicators for the planetary N body problem.
The code uses a second order symplectic integrator to advance the Hamiltonian flow of the …

The transit timing variations method is currently the most successful method to determine
dynamical masses and orbital elements for Earth-sized transiting planets. Precise mass …

We study the orbital evolution of a system of two super-Earths embedded in a protoplanetary
disk close to a first order resonance. We focus on a repulsion mechanism connected to wave …
