Revisited parameters for the twin bulge globular clusters NGC 6528 and NGC 6553
S. Ortolani, S. O. Souza, D. Nardiello +2
NGC 6528 and NGC 6553 are among the most metal-rich globular clusters in the Galactic bulge. They represent the upper end of the chemical enrichment in the Galaxy, and can inform o…
Combined Gemini-South and HST photometric analysis of the globular cluster NGC 6558. The age of the metal-poor population of the Galactic Bulge
S. O. Souza, M. Libralato, D. Nardiello +8
NGC~6558 is a low-galactic latitude globular cluster projected in the direction of the Galactic bulge. Due to high reddening, this region presents challenges in deriving accurate p…
A census of new globular clusters in the Galactic bulge
E. Bica, S. Ortolani, B. Barbuy +1
The number of known globular clusters in the Galactic bulge has been increasing steadily thanks to different new surveys. The aim of this study is to provide a census of the newly…
The Gaia-ESO Public Spectroscopic Survey: Motivation, implementation, GIRAFFE data processing, analysis, and final data products
G. Gilmore, S. Randich, C. C. Worley +165
The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to obtain astrophysical parameters and elemental abundances for 100,000 stars, including large representat…
Distribution of solids in the rings of the HD 163296 disk: a multiwavelength study
G. Guidi, A. Isella, L. Testi +15
In this paper we analyze new observations from ALMA and VLA, at a high angular resolution corresponding to 5 - 8 au, of the protoplanetary disk around HD 163296 to determine the du…
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…
