Exploring the dynamical state of Galactic open clusters using Gaia DR3 and observational parameters
M. S. Angelo, J. F. C. Santos, W. J. B. Corradi +1

Enlightening the dynamical evolution of Galactic open clusters: an approach using Gaia DR3 and analytical descriptions
M. S. Angelo, J. F. C. Santos, F. F. S. Maia +1
Most stars in our Galaxy form in stellar aggregates, which can become long-lived structures called open clusters (OCs). Along their dynamical evolution, their gradual depletion lea…

The VISCACHA survey -- IV. The SMC West Halo in 8D
B. Dias, M. C. Parisi, M. Angelo +18
The structure of the Small Magellanic Cloud (SMC) is very complex, in particular in the periphery that suffers more from the interactions with the Large Magellanic Cloud (LMC). A w…
Investigating Galactic binary cluster candidates with Gaia EDR3
M. S. Angelo, J. F. C. Santos, F. F. S. Maia +1
A number of stellar open cluster (OC) pairs in the Milky Way occupy similar positions in the phase space (coordinates, parallax and proper motions) and therefore may constitute phy…
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…
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…
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…
