Neighbors, Not Kin: Kinematic evidence for tidal tails from NGC 7492 along the Sagittarius stream
Camila Navarrete, Ãlvaro Rojas-Arriagada, Andrés E. Piatti +8
The formation, extension, and morphology of extra-tidal stars around globular clusters depend on the internal kinematics of the host cluster and the Galactic potential. Tracing the…
Pre-main Sequence B Stars Surrounding the Orion Nebula
P. H. F. B. Braz, A. Roman-Lopes, W. J. B. Corradi +6
Pre-main sequence (PMS) early-type stars are rare due to their rapid evolution. Confirming PMS B stars is accordingly valuable for constraining higher mass star formation scenarios…
Spatially resolved star formation history of Sextans dSph
Andrés E. Piatti
We present a spatially resolved archaeological reconstruction of the Sextans dwarf spheroidal (dSph) galaxy using deep DECam wide-field photometry and the PANCAKE CMD-fitting code.…
The apparent Large Magellanic Cloud star cluster age gap
Jonathan H. Klos, Andrés E. Piatti
In the Large Magellanic Cloud (LMC), there have been very few clusters observed with ages between 4 and 11 Gyr. This phenomenon is sometimes referred to as the `LMC age gap'. We co…
Recovering extra-tidal open cluster members via multi-elemental chemical tagging
Andrès E. Piatti
The identification of open cluster (OC) members has been revolutionized by high-precision Gaia astrometry, yet traditional kinematic membership selections remain inherently conserv…
3D kinematics of SMC star clusters: residual velocities disentangle kinematically perturbed clusters
Denis M. F. Illesca, Andrés E. Piatti, MatÃas Chiarpotti +1
Understanding the kinematic behaviour of the Small Magellanic Cloud (SMC) remains a challenge addressed by many authors using diverse approaches. Over time, increasing observationa…
