Global Spiral Modes in Star-Forming Gravitating Disks
Vladimir Korchagin, Christian Theis
Using 2D nonlinear simulations, we study the generation and nonlinear evolution of spiral structure in a star-forming multi-component gravitating disk. We confirm in agreement with…

On the evolution of shape in N-body simulations
Ch. Theis, R. Spurzem
A database on shape evolution of direct N-body models formed out of cold, dissipationless collapse is generated using GRAPE and HARP special purpose computers. Such models are impo…
