Post-Newtonian simulations of super-massive black hole binaries in galactic nuclei
I. Berentzen, M. Preto, P. Berczik +2
We present some preliminary results from recent numerical simulations that model the evolution of super-massive black hole (SMBH) binaries in galactic nuclei. Including the post-Ne…
Comparative study between N-body and Fokker-Planck simulations for rotating star clusters: I. Equal-mass system
Eunhyeuk Kim, Ilsang Yoon, Hyung Mok Lee +1
We have carried out N-body simulations for rotating star clusters with equal mass and compared the results with Fokker-Planck models. These two different approaches are found to pr…
NBODY meets stellar population - The HYDE-PARC Project
Andrea Borch, Rainer Spurzem, Jarrod Hurley
N-body simulations give us a rough idea of how the shape of a simulated object appears in three-dimensional space. From an observational point of view this may give us a misleading…
N-body Models of Rotating Globular Clusters
Andreas Ernst, Patrick Glaschke, Jose Fiestas +2
We have studied the dynamical evolution of rotating globular clusters with direct -body models. Our initial models are rotating King models; we obtained results for both equal-m…
Dynamics of Planetary Systems in Star Clusters
R. Spurzem, M. Giersz, D. C. Heggie +1
At least 10-15% of nearby sun-like stars have known Jupiter-mass planets. In contrast, very few planets are found in mature open and globular clusters such as the Hyades and 47 Tuc…
2D Fokker-Planck models of rotating clusters
J. Fiestas, R. Spurzem, E. Kim
Globular clusters rotate significantly, and with the increasing amount of detailed morphologicaland kinematical data obtained in recent years on galactic globular clusters many int…
