First evidence of a collision between two unrelated open clusters in the Milky Way

Andrés E. Piatti, Khyati Malhan

We report the first evidence of an on-going collision between two star clusters in our Galaxy, namely IC 4665 and Collinder 350. These are open clusters located at a distance of ~3…

DECam photometry reveals extra-tidal stars around the Milky Way globular cluster NGC 6864 (M75)

Andrés E. Piatti

Globular clusters are prone to lose stars while moving around the Milky Way. These stars escape the clusters and are distributed throughout extended envelopes or tidal tails. Howev…

Revisiting a detached stellar structure in the outer northeastern region of the Small Magellanic Cloud

Andrés E. Piatti

The outer northeastern region of the Small Magellanic Cloud (SMC) is populated by a shell-like overdensity whose nature was recently investigated. We analyzed twenty catalogued sta…

Residual velocities of Small Magellanic Cloud star clusters

Andrés E. Piatti

We analyzed the largest Small Magellanic Cloud (SMC) cluster sample (32) with proper motions and radial velocity measurements, from which we obtained their space velocity component…

Globular cluster candidates in the Sagittarius dwarf galaxy

Andrés E. Piatti

Recently, new Sagittarius (Sgr) dwarf galaxy globular clusters were discovered, which opens the question on the actual size of the Sgr globular cluster population, and therefore on…

The surroundings of the Milky Way globular cluster NGC 6809

Andrés E. Piatti

We study the outer regions of the Milky Way globular cluster NGC6809 based on Dark Energy Camera (DECam) observations, which reach nearly 6 mag below the cluster main sequence (MS)…

The kinematics of Small Magellanic Cloud star clusters

Andrés E. Piatti

We report results of proper motions of 25 known Small Magellanic Cloud (SMC) clusters (ages ~ 1 - 10 Gyr old) derived from Gaia EDR3 data sets. When these mean proper motions are g…

Revisiting newly Large Magellanic Cloud age gap star clusters

Andrés E. Piatti

Recently, a noticeable number of new star clusters was identified in the outskirts of the Large Magellanic Cloud (LMC) populating the so-called star cluster age gap, a space of tim…

APOGEE discovery of a chemically atypical star disrupted from NGC 6723 and captured by the Milky Way bulge

José G. Fernández-Trincado, Timothy C. Beers, Dante Minniti +26

The central (`bulge') region of the Milky Way is teeming with a significant fraction of mildly metal-deficient stars with atmospheres that are strongly enriched in cyanogen ($^{12}…

On the structure of Small Magellanic Cloud star clusters

Andrés E. Piatti

It has been recently shown from observational data sets the variation of structural parameters and internal dynamical evolution of star clusters in the Milky Way and in the Large M…

Signatures of tidal disruption in the Milky Way globular cluster NGC 6981 (M72)

A. E. Piatti, M. F. Mestre, J. A. Carballo-Bello +4

We study the outer regions of the Milky Way globular cluster NGC6981 from publicly available photometry and new Dark Energy Camera (DECam) observations, both reaching nearly 4…

Metallicities and ages for 35 star clusters and their surrounding fields in the Small Magellanic Cloud

W. Narloch, G. Pietrzyński, W. Gieren +13

In this work we study 35 stellar clusters in the Small Magellanic Cloud (SMC) in order to provide their mean metallicities and ages. We also provide mean metallicities of the field…
