Trojan Stars in the Galactic Center
Michiko Fujii, Masaki Iwasawa, Yoko Funato +1
We performed, for the first time, the simulation of spiral-in of a star cluster formed close to the Galactic center (GC) using a fully self-consistent -body model. In our model,…
The core radius of a star cluster containing a massive black hole
Douglas C. Heggie, Piet Hut, Shin Mineshige +2
(Simplified) We present a theoretical framework which establishes how the core radius of a star cluster varies with the mass of an assumed central black hole. Our result is that th…
Tidal Capture of Stars by Intermediate-Mass Black Holes
H. Baumgardt, C. Hopman, S. Portegies Zwart +1
Recent X-ray observations and theoretical modelling have made it plausible that some ultraluminous X-ray sources (ULX) are powered by intermediate-mass black holes (IMBHs). N-body…
A Dynamical Model for the Globular Cluster G1
Holger Baumgardt, Junichiro Makino, Piet Hut +2
We present a comparison between the observational data on the kinematical structure of G1 in M31, obtained with the Hubble WFPC2 and STIS instruments, and the results of dynamical…
Evolution of Compact Groups of Galaxies I. Merging Rates
E. Athanassoula, J. Makino, A. Bosma
We discuss the merging rates in compact groups of 5 identical elliptical galaxies. All groups have the same mass and binding energy. We consider both cases with individual halos an…
Time-Symmetrized Kustaanheimo-Stiefel Regularization
Y. Funato, P. Hut, S. McMillan +1
In this paper we describe a new algorithm for the long-term numerical integration of the two-body problem, in which two particles interact under a Newtonian gravitational potential…
