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…

Open cluster age calibration from colour-magnitude morphological indices using Gaia DR3 data
F. A. Ferreira, J. F. C. Santos, W. J. B. Corradi +2
Star clusters are crucial for understanding how stars evolve. Their colour-magnitude diagrams show the effects of stellar evolution of approximately coeval objects with the same ch…
