The only trace of the flyby left in the planet system, after about 10 4 yr, is a small misalignment, lower than 9В°, between the star equatorial plane and the planet orbit.Д¬onclusions. The planet is quickly dragged back within the disk by the tidal interaction with the gas. During the flyby both the disks are warped owing to the mutual interaction and to the stellar gravitational perturbations, but they quickly relax to a new orbital plane. The damping in eccentricity is slightly faster than in 2D models and it occurs on timescales on the order of a few kyr. This is mostly related to the mass exchange between the two disks at the encounter. We find that the amount of mass lost by the disk during the stellar flyby is less than in 2D models where a single disk was considered.

This allows us to test in full the ability of the disk to erase the effects of the stellar encounter. We focus on an extreme configuration where a very deep stellar flyby perturbs a Jovian planet on an external orbit. Different inclinations between the disks, planet orbit, and star trajectory have been considered to explore various encounter geometries.

We have modeled in 3D with the SPH code VINE, a system made of a solar-type star surrounded by a low density disk with a giant planet embedded in it approached on a hyperbolic encounter trajectory by a second star of similar mass and with its own disk. Since we perform 3D simulations, we can also test the inclination, excitation, and damping.

The time required to disperse stellar clusters is comparable to the circumstellar diskвЂ™s lifetime.

We explore whether the impulsive changes in the orbital elements of planets, caused by a hyperbolic stellar flyby, can be fully damped by the circumstellar disk surrounding the star. Stellar flybys in star clusters are suspected of affecting the orbital architecture of planetary systems causing eccentricity excitation and orbital misalignment between the planet orbit and the equatorial plane of the star.ДЄims.
