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 analysis of star clusters towards the W31 star-forming complex
Marina Bianchin, Eliade F. Lima, Eduardo Bica +3
The giant HII region W31 hosts the populous star cluster W31-CL and others projected on or in the surroundings. The most intriguing object is the stellar cluster SGR1806-20, which…
A Deep View of a Fossil Relic in the Galactic Bulge: The Globular Cluster HP1
L. O. Kerber, M. Libralato, S. O. Souza +7
HP1 is an -enhanced and moderately metal-poor bulge globular cluster with a blue horizontal branch. These combined characteristics make it a probable relic of the early star…
Halo intruders in the Galactic bulge revealed by HST and Gaia: the globular clusters Terzan 10 and Djorgovski 1
S. Ortolani, D. Nardiello, A. Pérez-Villegas +2
The low-latitude globular clusters Terzan 10 and Djorgovski 1 are vprojected in the Galactic bulge, in a Galactic region highly affected by extinction. A discrepancy of a factor of…
High-resolution abundance analysis of four red giants in the globular cluster NGC 6558
B. Barbuy, L. Muniz, S. Ortolani +8
NGC 6558 is a bulge globular cluster with a blue horizontal branch (BHB), combined with a metallicity of [Fe/H]~-1.0. It is similar to HP 1 and NGC 6522, which could be among the o…
High-resolution abundance analysis of red giants in the metal-poor bulge globular cluster HP~1
B. Barbuy, E. Cantelli, A. Vemado +10
The globular cluster HP~1 is projected at only 3.33 degrees from the Galactic center. Together with its distance, this makes it one of the most central globular clusters in the Mil…
