In the early phase of the Solar system evolution, while the outer planets migrated due to their interaction with a planetesimal disc, Jupiter may have crossed the 2:1 mean motion resonance with Saturn. It is well known that this dynamical event has profound consequences on the evolution of an alleged initial Trojan population of Jupiter. In...

We numerically explore planet formation around α Centauri A by focusing on the crucial planetesimals-to-embryos phase. Our approach is significantly improved with respect to the earlier work of Marzari & Scholl, since our deterministic N-body code computing the relative velocities between test planetesimals handles bodies with different size....

Recent studies have shown that α Centauri B might be, from an observational point of view, an ideal candidate for the detection of an Earth-like planet in or near its habitable zone (0.5-0.9 au). We study here if such habitable planets can form, by numerically investigating the planet-formation stage which is probably the most sensitive to...

We numerically investigate the possibility of planetesimal accretion in circumbinary discs, under the coupled influence of both stars' secular perturbations and friction due to the gaseous component of the protoplanetary disc. We focus on one crucial parameter: the distribution of encounter velocities between planetesimals in the 0.5-100 km...
