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…

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…

The elusive tidal tails of the Milky Way globular cluster NGC 7099

A. E. Piatti, J. A. Carballo-Bello, M. D. Mora +3

We present results on the extra-tidal features of the Milky Way globular cluster NGC 7099, using deep gr photometry obtained with the Dark Energy Camera (DECam). We reached nearly…

Strömgren metallicities for intermediate-age and old star clusters

Andrés E. Piatti

We report results that show that the straightforwardly star cluster metallicities obtained from Strömgren photometry is age-dependent and need to be corrected for further use…

The VISCACHA survey -- II. Structure of star clusters in the Magellanic Clouds periphery

J. F. C. Santos, F. F. S. Maia, B. Dias +11

We provide a homogeneous set of structural parameters of 83 star clusters located at the periphery of the Small Magellanic Cloud (SMC) and the Large Magellanic Cloud (LMC). The clu…

Discovery of rotation axis alignments in Milky Way globular clusters

Andrés E. Piatti

There is an increasing number of recent observational results which show that some globular clusters exhibit internal rotation while they travel along their orbital trajectories ar…

A binary star sequence in the outskirts of the disrupting Galactic open cluster UBC 274

Andrés E. Piatti

We report the identification of a numerous binary star population in the recently discovered ~3 Gyr old open cluster UBC 274. It becomes visible once the cluster color-magnitude di…

On the tidal tails of Milky Way globular clusters

Andrés E. Piatti, Julio A. Carballo-Bello

We report on the search for overall kinematical or structural conditions that have allowed some Milky Way globular clusters to presently develop tidal tails. For this purpose, we b…
