Finding clusters of young stars using “finite mixture models”
Layered structure to the Orion Nebula
X-ray SelectedIRE Selected
Typical Subcluster Properties
Embedded Subclusters tend to be smaller
Typical cluster cores have r=0.18 pc.
Strong relation between core radius and central density.
Similar to results interpreted by Pfalzner et al. (2009) as cluster expansion.
Dynamical properties of subclusters.
