In this way, an indication of the fraction of metal-poor bulge stars that originated from globular clusters can be determined. We observed and analyzed stars in and around BH261, an understudied globular cluster in the bulge. From seven giants within the tidal radius of the cluster, we measured an average heliocentric radial velocity of RV=-61{+/-}2.6km/s with a radial velocity dispersion of {sigma}=6.1{+/-}1.9km/s. The large velocity dispersion may have arisen from tidal heating in the cluster's orbit about the Galactic center, or because BH261 has a high dynamical mass as well as a high mass-to-light ratio. From spectra of five giants, we measure an average metallicity of [Fe/H]=-1.1{+/-}0.2dex. We also spectroscopically confirm an RR Lyrae star in BH 261, which yields a distance to the cluster of 7.1{+/-}0.4kpc. Stars with 3D velocities and metallicities consistent with BH261 reaching to ~0.5deg from the cluster are identified. A handful of these stars are also consistent with the spatial distribution of potential debris from models focusing on the most recent disruption of the cluster.2024AJ....167...21Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/167/21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)III/279 : RAVE 5th data release (Kunder+, 2017)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)VII/195 : Globular Clusters in the Milky Way (Harris, 1996)VII/202 : Globular Clusters in the Milky Way (Harris, 1997)J/MNRAS/364/179 : BVI photometry of 8 open clusters (Carraro+, 2005)J/ApJS/197/29 : Chemical compositions of 11 RR Lyrae (For+, 2011)J/A+A/534/A136 : Halo red giants from the SEGUE survey (Martell+, 2011)J/A+A/540/A27 : Spectroscopy in Galactic globular clusters (Saviane+, 2012)J/A+A/549/A147 : Abund of microlensed bulge dwarf stars.
