Precise distances from OGLE-IV member RR Lyrae stars in six bulge globular clusters
R. A. P. Oliveira, S. Ortolani, B. Barbuy +6
Context. RR Lyrae stars are useful standard candles allowing one to derive accurate distances for old star clusters. Based on the recent catalogues from OGLE-IV and Gaia Early Data…
Photo-chemo-dynamical analysis and the origin of the bulge globular cluster Palomar 6
Stefano O. Souza, Marica Valentini, Beatriz Barbuy +7
Palomar 6 (Pal~6) is a moderately metal-poor globular cluster projected towards the Galactic bulge. A full analysis of the cluster can give hints on the early chemical enrichment o…
UVES analysis of red giants in the bulge globular cluster NGC 6522
B. Barbuy, E. Cantelli, L. Muniz +10
NGC 6522 is a moderately metal-poor bulge globular cluster ([Fe/H]1.0), and it is a well-studied representative among a number of moderately metal-poor blue horizontal bra…
Abundance Patterns of and Neutron-capture Elements in the Helmi Stream
Guilherme Limberg, Rafael M. Santucci, Silvia Rossi +6
We identified 8 additional stars as members of the Helmi stream (HStr) in the combined GALAH+ DR3 and EDR3 catalog. By consistently reevaluating claimed members from the lit…
CAPOS: the bulge Cluster APOgee Survey II. The Intriguing "Sequoia" Globular Cluster FSR 1758
María Romero-Colmenares, José G. Fernández-Trincado, Doug Geisler +15
We present results from a study of fifteen red giant members of the intermediate-metallicity globular cluster (GC) FSR 1758 using high-resolution near-infrared spectra collected wi…
The VISCACHA survey -- III. Star clusters counterpart of the Magellanic Bridge and Counter-Bridge in 8D
B. Dias, M. S. Angelo, R. A. P. Oliveira +15
Context. The interactions between the SMC and LMC created the Magellanic Bridge, a stream of gas and stars pulled out of the SMC towards the LMC about 150 Myr ago. The tidal counte…
Gemini/Phoenix H-band analysis of the globular cluster AL3
B. Barbuy, H. Ernandes, S. O. Souza +9
The globular cluster AL~3 is old and located in the inner bulge. Three individual stars were observed with the Phoenix spectrograph at the Gemini South telescope. The wavelength re…
VVV CL001: Likely the Most Metal-Poor Surviving Globular Cluster in the Inner Galaxy
José G. Fernández-Trincado, Dante Minniti, Stefano O. Souza +11
We present the first high-resolution abundance analysis of the globular cluster VVV~CL001, which resides in a region dominated by high interstellar reddening towards the Galactic B…
APOGEE discovery of a chemically atypical star disrupted from NGC 6723 and captured by the Milky Way bulge
José G. Fernández-Trincado, Timothy C. Beers, Dante Minniti +26
The central (`bulge') region of the Milky Way is teeming with a significant fraction of mildly metal-deficient stars with atmospheres that are strongly enriched in cyanogen ($^{12}…
