Numerical Simulations of Regolith Sampling Processes
Christoph M. Schäfer, Samuel Scherrer, Robert Buchwald +3
We present recent improvements in the simulation of regolith sampling processes in microgravity using the numerical particle method smooth particle hydrodynamics (SPH). We use an e…
Triggering Sublimation-Driven Activity of Main Belt Comets
Nader Haghighipour, Thomas Maindl, Christoph Schaefer +2
It has been suggested that the comet-like activity of Main Belt Comets are due to the sublimation of sub-surface water-ice that has been exposed as a result of their surfaces being…
A smooth particle hydrodynamics code to model collisions between solid, self-gravitating objects
Christoph M. Schäfer, Sven Riecker, Thomas I. Maindl +3
Modern graphics processing units (GPUs) lead to a major increase in the performance of the computation of astrophysical simulations. Owing to the different nature of GPU architectu…
Collisions of planetesimals and formation of planets
Rudolf Dvorak, Thomas I. Maindl, Áron Süli +3
We present preliminary results of terrestrial planet formation using on the one hand classical numerical integration of hundreds of small bodies on CPUs and on the other hand -- fo…
Planetary Systems and the Formation of Habitable Planets
Rudolf Dvorak, Thomas I. Maindl, Christoph Burger +2
As part of a national scientific network 'Pathways to Habitability' the formation of planets and the delivery of water onto these planets is a key question as water is essential fo…
Fragmentation of colliding planetesimals with water content
Thomas I. Maindl, Rudolf Dvorak, Christoph Schäfer +1
We investigate the outcome of collisions of Ceres-sized planetesimals composed of a rocky core and a shell of water ice. These collisions are not only relevant for explaining the f…
