Quantifying kinematic substructure in star-forming regions with statistical tests of spatial autocorrelation
Becky Arnold, Nicholas J. Wright, Richard J. Parker
We investigate whether spatial-kinematic substructure in young star-forming regions can be quantified using Moran's statistic. Its presence in young star clusters would provide…
The velocity structure of Cygnus OB2
Becky Arnold, Simon P. Goodwin, Nick J. Wright
The kinematic structure of the Cygnus OB2 association is investigated. No evidence of expansion or contraction is found at any scale within the region. Stars that are within …
Dynamical evolution of star-forming regions: III. Unbound stars and predictions for Gaia
Christina Schoettler, Richard J. Parker, Becky Arnold +3
We use -body simulations to probe the early phases of the dynamical evolution of star-forming regions and focus on mass and velocity distributions of unbound stars. In this para…
A method to analyse velocity structure
Becky Arnold, Simon Goodwin
We present a new method of analysing and quantifying velocity structure in star forming regions suitable for the rapidly increasing quantity and quality of stellar position-velocit…
How do binary clusters form?
Becky Arnold, Simon P. Goodwin, Daniel W. Griffiths +1
Approximately 10 per cent of star clusters are found in pairs, known as binary clusters. We propose a mechanism for binary cluster formation; we use N-body simulations to show that…
