Dynamical mass segregation on a very short timescale
R. J. Allison, S. P. Goodwin, R. J. Parker +3
We discuss the observations and theory of star cluster formation to argue that clusters form dynamically cool (subvirial) and with substructure. We then perform an ensemble of simu…
Using the minimum spanning tree to trace mass segregation
Richard J. Allison, Simon P. Goodwin, Richard J. Parker +3
We present a new method to detect and quantify mass segregation in star clusters. It compares the minimum spanning tree (MST) of massive stars with that of random stars. If mass se…
Diffuse, Non-Thermal X-ray Emission from the Galactic Star Cluster Westerlund 1
Michael P. Muno, Casey Law, J. Simon Clark +4
We present the diffuse X-ray emission identified in Chandra observations of the young, massive Galactic star cluster Westerlund 1. After removing point-like X-ray sources down to a…
The ecology of star clusters and intermediate mass black holes in the Galactic bulge
Simon Portegies Zwart, Holger Baumgardt, Stephen L. W. McMillan +3
We simulate the inner 100pc of the Milky-Way Galaxy to study the formation and evolution of the population of star clusters and intermediate mass black holes. For this study we per…
The Effect of Pre-Main Sequence Stars on Star Cluster Dynamics
R. Wiersma, A. Sills, S. Portegies Zwart
We investigate the effects of the addition of pre-main sequence evolution to star cluster simulations. We allowed stars to follow pre-main sequence tracks that begin at the deuteri…
Planets in triple star systems--the case of HD188753
Simon Portegies Zwart, Steve McMillan
We consider the formation of the recently discovered ``hot Jupiter'' planet orbiting the primary component of the triple star system HD188753. Although the current outer orbit of t…
