In June 1976, a pristine meteorite stone weighing approximately 1 kg, fully covered with a fresh black fusion crust, was collected on a mountain road in the high-altitude Alpine environment. The recovery took place while clearing the remnants of a sn

GENGA II: GPU planetary N-body simulations with non-Newtonian forces and high number of particles

Autor: Grimm, Simon L., Stadel, Joachim G., Brasser, Ramon, Meier, Matthias M. M., Mordasini, Christoph

We present recent updates and improvements of the graphical processing unit (GPU) N-body code GENGA. Modern state-of-the-art simulations of planet formation require the use of a very high number of particles to accurately resolve planetary growth and
