Below are some examples of simulations run within our group.

Planetesimals around the binary Kepler 34


Description of video:

Perturbations from the orbit of the binary star excite eccentricity waves in the planetesimal disc.
See Lines et al. 2014

Moon formation


Description of video:

Post-impact circumterrestial disk evolution, showing clumps growing inside the Roche limit. These are elongated by Keplerian shear, and spiral arms are formed. The tips of the spiral arms collapse to form moonlets, which then eventually accrete into a moon.

Protoplanet growth in the Grand Tack


Description of video:

Evolution of eccentricity and inclination vs semi-major axis for growing terrestrial planet embryos under the Grand Tack model.
See Carter et al. 2015

Saturn's B Ring


Description of video:

Local patch simulation (interparticle gravity and collisions are enabled) with periodic boundary conditions, showing the structure - wakes, striations - that readily form.

Protoplanet growth in a calm disc


Description of video:

Evolution of mass vs semi-major axis for growing terrestrial planet embryos in a calm disc not perturbed by giant planets.
See Carter et al. 2015

Circumbinary gas disc around Kepler 34


Description of video:

Perturbations caused by the orbit of the binary stars cause the gas disc to become eccentric.
See Lines et al. 2015
