- Abstract
We present results of n-body and smooth particle hydrodynamics (SPH) simulations, exploring the crater formation process of the Valhalla crater located on the Jovian Moon Callisto. We compute typical impact velocities and impact angles which we then use as input for the SPH simulations to reconstruct the actual crater formation. Using a three-layered Callisto model with a subsurface ocean, we find significant connections between the crater formation process and the interaction with the subsurface ocean. We also investigate the properties of the projectile and numerical effects of low-resolution projectiles in the context of SPH.
