Inverse mass segregation in Taurus
I will present results of a search for mass segregation in Taurus using the new Minimum Spanning Tree (MST) technique. This method compares the MSTs of any chosen subset of objects to the MSTs of random objects in a cluster. In contrast to Orion, where strong mass segregation is observed, the most massive stars in Taurus are preferentially located on the outskirts of the stellar aggregates. We also find that most low-mass stars are mass segregated when compared to random sets of stars.
