Astrophysical properties of newly discovered Magellanic Cloud star clusters
Andrés E. Piatti
New star cluster candidates projected toward the Large and Small Magellanic Clouds (L/SMC) have been recently discovered from relatively deep imaging surveys. We here conduct a sou…
Dependence of the old star clusters' dynamical clock on the host galaxy gravitational field
Andrés E. Piatti
I report outcomes of the analysis of the parameter, which measures the level of radial segregation of blue straggler stars in old star clusters, commonly known as the dynamic…
The search for extratidal star candidates around Galactic globular clusters NGC 2808, NGC 6266, and NGC 6397 with {\textit{Gaia}} DR2 astrometry
Richa Kundu, Camila Navarrete, José G. Fernández-Trincado +5
Context. Extratidal stars are stellar bodies that end up outside the tidal radius of a cluster as a result of internal processes or external forces acting upon it. The presence and…
Multiple populations of Hbeta emission line stars in the Large Magellanic Cloud cluster NGC1971
Andrés E. Piatti
We revisited the young Large Magellanic Cloud star cluster NGC1971 with the aim of providing additional clues to our understanding of its observed extended Main Sequence turnoff (e…
Different Sodium enhancements among multiple populations of Milky Way globular clusters
Andrés E. Piatti
We searched for trails to understand the different Na abundances measured in first and second generation stars of ancient Milky Way globular clusters. For that purpose, we gathered…
The disruption of the low-mass globular cluster E3
Julio A. Carballo-Bello, Ricardo Salinas, Andrés E. Piatti
We use {\it Gaia} DR2 photometry and proper motions to search for the hypothetical tidal tails of the Galactic globular cluster E\,3. Using a modified version of a classical decont…
