A combined HST and JWST analysis of the stellar population in Draco II
Axelle C. Raffin, Giacomo Cordoni, Helmut Jerjen +5
Draco II (Dra II) is one of the faintest and most metal-poor Milky Way satellites known, yet its nature as either an ultra-faint dwarf galaxy or an extended globular cluster remain…
Tracing M22's origins: Spatial and chemical constraints on its formation history
Emanuele Dondoglio, Antonino P. Milone, Randa Asa'd +9
Globular clusters (GCs) are well known to host stellar populations characterized by light-element variations. A subset of Galactic GCs, beyond such 'canonical' populations, contain…
High-fidelity stellar extinction with Gaia and APOGEE -- I. The method and a new extinction curve
Jie Yu, Luca Casagrande, John A. Taylor +9
The scarcity of high-fidelity extinction measurements remains a bottleneck in deriving accurate stellar properties from Gaia parallaxes. In this work, we aim to derive precision ex…
Detailed Abundance Determination of Metal-Poor Stars with X-Shooter I. Unusual Chemistry in Halo Stars
Benjamin D. C. Lowe, Thomas Nordlander, Luca Casagrande +5
We present a detailed chemical analysis study of 16 candidate metal-poor stars, previously identified with 2dF + AAOmega, using X-Shooter spectra and the Korg 1D local thermodynami…
Rubin Data Preview 1: Extending the View of Unresolved Binary Stars in 47 Tucanae
Giacomo Cordoni, Luca Casagrande, Helmut Jerjen
Until now, the study of unresolved main sequence binary stars in globular clusters has been possible almost exclusively in their central regions with deep Hubble Space Telescope (H…
The Rise of the Milky Way Disk through EMP Stars
B. Lowe, T. Nordlander, L. Casagrande +6
We present a chemo-dynamical study conducted with 2dFAAOmega of Gaia DR3 non-variable candidate metal-poor stars that lie in the direction of the Galactic plane. Our…
