Monte Carlo Simulations of Star Clusters - VI. The globular cluster NGC 6397
M. Giersz, D. C. Heggie
We describe Monte Carlo models for the dynamical evolution of the nearby globular cluster NGC 6397. The code includes treatments of two-body relaxation, most kinds of three- and fo…
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 search for spectroscopic binaries in the galactic globular cluster M4. Based on 5973 individual spectra collected at VLT
V. Sommariva, G. Piotto, M. Rejkuba +4
We present a large multi-epoch high resolution spectroscopic investigation for the search of binary candidates in the Galactic Globular Cluster (GGC) M4. The aim of our work is the…
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…
Modelling individual globular clusters
D. C. Heggie, M. Giersz
Astronomers have constructed models of globular clusters for over 100 years. These models mainly fall into two categories: (i) static models, such as King's model and its variants,…
