On the relationship between instability and Lyapunov times for the 3-body problem
D. J. Urminsky, D. C. Heggie
In this study we consider the relationship between the survival time and the Lyapunov time for 3-body systems. It is shown that the Sitnikov problem exhibits a two-part power law r…
A multiphysics and multiscale software environment for modeling astrophysical systems
Simon Portegies Zwart, Steve McMillan, Stefan Harfst +2
We present MUSE, a software framework for combining existing computational tools for different astrophysical domains into a single multiphysics, multiscale application. MUSE facili…
Monte Carlo Simulations of Star Clusters - V. The globular cluster M4
Mirek Giersz, Douglas Heggie
We describe Monte Carlo models for the dynamical evolution of the nearby globular cluster M4. The code includes treatments of two-body relaxation, three- and four-body interactions…
Monte Carlo Simulations of Star Clusters - IV. Calibration of the Monte Carlo Code and Comparison with Observations for the Open Cluster M67
Mirek Giersz, Douglas C. Heggie, Jarrod R. Hurley
We outline the steps needed in order to incorporate the evolution of single and binary stars into a particular Monte Carlo code for the dynamical evolution of a star cluster. We ca…
