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…
FSR 1776: a new globular cluster in the Galactic bulge?
B. Dias, T. Palma, D. Minniti +6
(ABRIDGED) Recent near-IR surveys have uncovered a plethora of new globular cluster (GC) candidates towards the Milky Way bulge. These new candidates need to be confirmed as real G…
12C/13C ratio and CNO abundances in the classical very old metal-poor dwarf HD 140283
M. Spite, F. Spite, B. Barbuy
The isotope abundances provide powerful diagnostics of the chemical enrichment in our Galaxy. The star HD 140283 is one of the best-studied very metal-poor dwarf stars. It is very…
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…
