Chemo-dynamical stratification of the Galactic disc using \emph{Gaia}-ESO open clusters
Casmir O. Obasi, M. Gómez, J. G. Fernández-Trincado +5
Understanding how the Milky Way disc assembled and evolved requires tracing the coupled evolution of stellar chemistry and orbital structure over time. Open clusters, as coeval ste…
Revealing the Origins of Galactic Globular Clusters via Their Mg-Al Abundances
Shihui Lin, Baitian Tang, Genghao Liu +4
Many Galactic globular clusters (GCs) originated in diverse host galaxies before being subsequently incorporated into the Milky Way through hierarchical galaxy assembly. Identifyin…
A Galactic Self-Portrait: Density Structure and Integrated Properties of the Milky Way Disk
Julie Imig, Jon A. Holtzman, Gail Zasowski +23
The evolution history of the Milky Way disk is imprinted in the ages, positions, and chemical compositions of individual stars. In this study, we derive the intrinsic density distr…
Measuring and modelling the Splash with APOGEE/Gaia and ARTEMIS
Shobhit Kisku, Ricardo P. Schiavon, Andreea S. Font +6
Using combined data from SDSS-IV/APOGEE and Gaia, we study the chemo-dynamical properties of the Splash population in comparison with those of the high-alpha disc. We investigate a…
The VISCACHA Survey: XIII. The extended main-sequence turn-off in intermediate-age low-mass clusters
Stefano Souza, Angeles Pérez-Villegas, Bruno Dias +16
The extended main-sequence turn-off (eMSTO) is a well-known feature observed in young and intermediate-age star clusters, characterized by a significant broadening of the main-sequ…
Open cluster members in APOGEE DR17 I. Dynamics and star members
R. Guerço, D. Souto, J. G. Fernández-Trincado +7
Context. Open clusters (OCs) are groups of stars formed from the same cloud of gas and cosmic dust. They play an important role in studies of star formation and evolution and our u…
