The dawn is quiet II: Gaia XP constraints on the Milky Way's proto-Galaxy from very metal-poor MDF tails
Boquan Chen, Matthew D. A. Orkney, Yuan-Sen Ting +1
The earliest phase of the Milky Way's evolution involved a transition from a dispersion-supported proto-galaxy to a rotationally supported disk. A key chemical signature of this tr…
Discovery of A Starburst in the Early Milky Way at [Fe/H]
Boquan Chen, Matthew Orkney, Yuan-Sen Ting +1
We present an analysis of very metal-poor (VMP) and metal-poor stars () in the Gaia BP/RP or XP catalog, which reveals two distinct metallicity distri…
C3PO IV: co-natal stars depleted in refractories are magnetically more active -- possible imprints of planets
Jie Yu, Yuan-Sen Ting, Luca Casagrande +14
Chemical abundance anomalies in twin stars have recently been considered tell-tale signs of interactions between stars and planets. While such signals are prevalent, their nature r…
The GALAH Survey: Data Release 4
S. Buder, J. Kos, E. X. Wang +36
The stars of the Milky Way carry the chemical history of our Galaxy in their atmospheres as they journey through its vast expanse. Like barcodes, we can extract the chemical finger…
