Globular Clusters Lost by the Sagittarius Dwarf Spheroidal Galaxy.

ARAKELYAN N.R., PILIPENKO S.V. and SHARINA M.E.

Abstract (from CDS):

In this work a search was carried out for globular clusters belonging to the Sagittarius (Sgr) tidal stream using the analysis of spatial positions, radial velocities relative to the Galactic Standard of Rest (VGSR), proper motions and ratio of "age-metallicity" ([Fe/H]) for globular clusters and for stars in the tidal stream. As a result, three categories of globular clusters were obtained: A - most certainly in the stream: Terzan 8, Whiting 1, Arp 2, NGC 6715, Terzan 7, Pal 12; B - kinematic outliers: Pal 5, NGC 5904, NGC 5024, NGC 5053, NGC 5272, NGC 288; C - lowest rank candidates: NGC 6864, NGC 5466, NGC 5897, NGC 7492, NGC 4147.
