Descripción
The Small Magellanic Cloud (SMC) has been tidally shaped by the interaction with the Large Magellanic Cloud (LMC). The scopeof such an interaction has recently been studied from different astrophysical properties of its star cluster population, which point tostar clusters placed remarkably outside the known extension of the galaxy. In this work we report results for three of the recently iden-tified most external SMC star clusters, OGLE-CL-SMC0133, OGLE-CL-SMC0237, and Lindsay 116, using deep GEMINI GMOSimaging. Once we confidently cleaned their color-magnitude diagrams from field star contamination, we estimated their fundamentalparameters applying likelihood techniques. We also derived their structural parameters from normalized star number density radialprofiles. Based on Gaia astrometric data, complemented with kinematics information available in the literature, we computed the 3Dcomponents of their space velocities. With similar ages (∼ 2.2 Gyr) and moderately metal-poor overall abundances ([Fe/H] = -1.0 --0.7 dex), OGLE-CL-SMC0237 is placed at 2.6 kpc from the SMC center and shares its disk rotation; OGLE-CL-SMC0133 is locatedat 7.6 kpc from the galaxy center and exhibits a kinematics marginally similar to the SMC rotation disk, while Lindsay 116 placed at15.7 kpc from the center of the SMC is facing strong perturbations of its orbital motion with respect to an ordered rotational trajectory.Furthermore, its internal dynamical evolution would seem to be accelerated –it seems kinematically older– in comparison with starclusters in the outskirts of relatively isolated galaxies. These outcomes lead to conclude that Lindsay 116 is subject to LMC tides.
