Hierarchical formation of Westerlund 1: a collapsing cluster with no primordial mass segregation?
Mario Gennaro, Simon P. Goodwin, Richard J. Parker +2
We examine the level of substructure and mass segregation in the massive, young cluster Westerlund 1. We find that it is relatively smooth, with little or no mass segregation, but…
On the Origin of Mass Segregation in NGC 3603
Xiaoying Pang, Eva K. Grebel, Richard J. Allison +5
We present deep Hubble Space Telescope/Wide Field and Planetary Camera 2 photometry of the young HD 97950 star cluster in the giant H {\sc ii} region NGC 3603. The data were obtain…
Testing the initial conditions and dynamical evolution of star clusters using Gaia - I
Richard J. Allison
We investigate how the properties of escaping stars are related to the initial conditions of their birth clusters. We find that the number of escaping stars, their spatial distribu…
The evolution of binary populations in cool, clumpy star clusters
Richard J. Parker, Simon P. Goodwin, Richard J. Allison
Observations and theory suggest that star clusters can form in a subvirial (cool) state and are highly substructured. Such initial conditions have been proposed to explain the leve…
On the formation of trapezium-like systems
Richard Allison, Simon Goodwin
We investigate the formation and evolution of high-order massive star multiples similar to the Trapezium in the Orion Nebula Cluster. We perform ensembles of N-body simulations of…
On the mass segregation of stars and brown dwarfs in Taurus
Richard J. Parker, Jerome Bouvier, Simon P. Goodwin +4
We use the new minimum spanning tree (MST) method to look for mass segregation in the Taurus association. The method computes the ratio of MST lengths of any chosen subset of objec…
