Abstract (from CDS):
We apply the method to the Orion Nebula Cluster (ONC) and show that the method is able to detect the mass segregation in the Trapezium with a `mass segregation ratio (MSR)' ΛMSR= 8.0±3.5 (where ΛMSR= 1 is no mass segregation) down to 16M☉, and also that the ONC is mass segregated at a lower level (∼2.0±0.5) down to 5M☉. Below 5M☉ we find no evidence for any further mass segregation in the ONC.
