Applications from Astrophysics
Here we present a choice of impressive projects from astrophysics which have been carried out on GCS supercomputers.
World's Largest Simulation of Supersonic, Compressible Turbulence
To advance the so far limited knowledge of density probability distribution function and the power spectrum of compressible, supersonic turbulence, a team of astrophysicists compared hydrodynamic models with numerical resolutions of 2563–40963 mesh points and with two distinct driving mechanisms, solenoidal (divergence-free) driving and compressive (curl-free) driving. By doing so, the scientists ran the world's largest simulation of supersonic turbulence on GCS supercomputers.

Gas Induced Orbital Decay of Binary Systems
Using hydrodynamic simulations on GCS supercomputers, a team of scientists from the Max-Planck-Institute for Radio Astronomy, Bonn, and Jülich Supercomputing Centre investigates the influences of surrounding gas onto the period of binary systems.

Three-dimensional Simulations of Supernova Explosions
Massive stars end their lives as core-collapse supernovae when the stellar core implodes to a neutron star and the stellar envelope is expelled. Using computer models, we have simulated the mixing processes occurring during the explosion without assuming any symmetry.

Star Formation in Extreme Conditions
Numerical simulations are a crucial tool to understand the physics of gas turbulence and star formation: there is no analytic theory. More than six decades of spatial scales need to be described, which is best done with "adaptive resolution" codes on supercomputers.
