Isolated massive stars in the Galactic Center: The dynamic contribution from the Arches and Quintuplet star clusters.

HABIBI M., STOLTE A. and HARFST S.

Abstract (from CDS):

Recently, more than 100 Wolf-Rayet and OB stars were identified in the Galactic center. About a third of these sources are not spatially associated with any of the known star clusters in this region. We probe the distribution of drifted sources in numerical models of the massive clusters in the Galactic center and compare it to the observed distribution of isolated massive sources in this region. We find that stars as massive as 100M☉ drift away from the center of each cluster by up to ∼60pc using the cluster models. Our best model reproduces ∼60% of the known isolated massive stars out to 80pc from the center of the Arches cluster. This number increases to 70-80% when we only consider the region that is ∼20pc from the Arches cluster.
