Pre-main Sequence B Stars Surrounding the Orion Nebula
P. H. F. B. Braz, A. Roman-Lopes, W. J. B. Corradi +6
Pre-main sequence (PMS) early-type stars are rare due to their rapid evolution. Confirming PMS B stars is accordingly valuable for constraining higher mass star formation scenarios…
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
Galactic open clusters (OCs) are subject to internal and external destructive effects that gradually deplete their stellar content, leaving imprints on their structure. To investig…

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…

We present the analysis of three faint clusters of the Small Magellanic Cloud RZ82, HW42 and RZ158. We employed the SOAR telescope instrument SAM with adaptive optics, allowing us…
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

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…
