The Milky Way Bulge Extra-Tidal Star Survey: NGC 6569

Joanne Hughes, Andrea Kunder, Kevin Covey +25

We present spectroscopic evidence for tidal debris associated with the bulge globular cluster NGC 6569, based on medium-resolution (R ~ 11,000) Anglo-Australian Telescope spectra o…

CAPOS: The bulge Cluster APOgee Survey VIII. Final ASPCAP results for all clusters

Doug Geisler, Cesar Muñoz, Sandro Villanova +12

Bulge globular clusters(BGCs) are exceptional tracers of the formation and chemodynamical evolution of this oldest Galactic component. However, until now, observational difficultie…

The Galactic Bulge exploration VI.: Gaia Enceladus/Sausage RR Lyrae stars in the inner-central stellar halo of the Milky Way

Andrea Kunder, Zdenek Prudil, Antonela Monachesi +6

We present a view of the stellar halo in the inner-central regions of the Milky Way (R <~ 10 kpc) mapped by RR Lyrae stars. The combined BRAVA-RR/APOGEE RR Lyrae catalog is used to…

The Galactic Bulge exploration V.: The secular spherical and X-shaped Milky Way bulge

Z. Prudil, V. P. Debattista, L. Beraldo e Silva +9

In this work, we derive systemic velocities and subsequently orbits for 8456 RR~Lyrae stars. We identify interlopers from other Milky Way (MW) structures, which amount to 22 percen…

The Galactic Bulge exploration III.: Calcium Triplet Metallicities for RR Lyrae Stars

Andrea Kunder, Zdenek Prudil, Claire Skaggs +5

RR Lyrae stars are excellent tracers of stellar populations for old, metal-poor components in the Milky Way Galaxy and the Local Group. Their luminosities have a metallicity-depend…

RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99

Evan Butler, Andrea Kunder, Zdenek Prudil +16

Patchick 99 is a candidate globular cluster located in the direction of the Galactic bulge, with a proper motion almost identical to the field and extreme field star contamination.…
