Investigating Galactic binary cluster candidates with Gaia EDR3

Autor: M S Angelo, J F C Santos, F F S Maia, W J B Corradi

Publikováno v: Monthly Notices of the Royal Astronomical Society. 510:5695-5724

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 physically interacting systems. The characterization of such objects base

Enlightening the dynamical evolution of Galactic open clusters: an approach using Gaia DR3 and analytical descriptions

Autor: M S Angelo, J F C Santos Jr., F F S Maia, W J B Corradi

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 leave some imprints on their structure. In this work, we employed astrome

Characterizing low-contrast Galactic open clusters with Gaia Data Release 2

Autor: M S Angelo, W. J. B. Corradi, J. F. C. Santos

Publikováno v: Monthly Notices of the Royal Astronomical Society. 493:3473-3489

In this study, we characterized 16 objects previously classified as faint or low-contrast Galactic open clusters (OCs). We employed parameters associated with the dynamical evolution of the OCs: the core (rc), tidal (rt) and half-mass (rhm) radii, ag

Ca II Triplet Spectroscopy of Small Magellanic Cloud Red Giants. VI. Analysis of chemical properties of the Main Body

Autor: B. J. De Bortoli, M. C. Parisi, L. P. Bassino, D. Geisler, B. Dias, G. Gimeno, M. S. Angelo, F. Mauro

Aims. In this paper we analyze the chemical evolution of the main body of the SMC, adding six additional clusters to previously published samples, based on homogeneously determined and accurate metallicities. Methods. We derived radial velocities and

Nearly coeval intermediate-age Milky Way star clusters at very different dynamics evolutionary stages

We report astrophysical properties of 12 Milky Way open clusters located beyond the circle around the Sun where the number of catalogued open clusters is thought to be statistically complete. By using deep optical photometry, we estimated their ages

Characterizing dynamical states of Galactic open clusters with Gaia DR2

Autor: W. J. B. Corradi, M S Angelo, F. A. Ferreira, J. F. C. Santos, F. F. S. Maia

In this work, we investigate the dynamical properties of 38 Galactic open clusters: 34 of them are located at low Galactic latitudes (|b| < 10$^{\circ}$) and are projected against dense stellar fields; the other 4 comparison objects present clearer c

Discovery and astrophysical properties of Galactic open clusters in dense stellar fields using Gaia DR2

Autor: F. A. Ferreira, W. J. B. Corradi, F. F. S. Maia, M S Angelo, J. F. C. Santos

We report the discovery of 25 new open clusters resulting from a search in dense low galactic latitude fields. We also provide, for the first time, structural and astrophysical parameters for the new findings and 34 other recently discovered open clu
