Structural parameters and blue stragglers in Sagittarius dwarf spheroidal galaxy globular clusters.
SALINAS R., JILKOVA L., CARRARO G., CATELAN M. and AMIGO P.
Abstract (from CDS):
Blue stragglers are identified in the four clusters, and their spatial distribution is compared to those of horizontal branch and red giant branch stars. The blue straggler properties do not provide evidence of mass segregation in Terzan 8, while Arp 2 probably shares the same status, although with less confidence. In the case of NGC 5634 and Palomar 12, blue stragglers are significantly less populous, and their analysis suggests that the two clusters have probably undergone mass segregation.
