Evidence of Truly Young high- Dwarf Stars
Yuxi Lu, Isabel L. Colman, Maryum Sayeed +14
The existence of high- stars with inferred ages < 6 Gyr has been confirmed recently with large spectroscopic and photometric surveys. However, stellar mergers or binary interact…
Discovery and Spectroscopic Confirmation of Aquarius III: A Low-Mass Milky Way Satellite Galaxy
W. Cerny, A. Chiti, M. Geha +37
We present the discovery of Aquarius III, an ultra-faint Milky Way satellite galaxy identified in the second data release of the DECam Local Volume Exploration (DELVE) survey. Base…
A Pride of Satellites in the Constellation Leo? Discovery of the Leo VI Milky Way Satellite Galaxy with DELVE Early Data Release 3
C. Y. Tan, W. Cerny, A. Drlica-Wagner +32
We report the discovery and spectroscopic confirmation of an ultra-faint Milky Way (MW) satellite in the constellation of Leo. This system was discovered as a spatial overdensity o…
Unveiling the purely young star formation history of the SMC's northeastern shell from colour-magnitude diagram fitting
Joanna D. Sakowska, Noelia E. D. Noël, Tomás Ruiz-Lara +12
We obtain a quantitative star formation history (SFH) of a shell-like structure ('shell') located in the northeastern part of the Small Magellanic Cloud (SMC). We use the Survey of…
The Extremely Metal Rich Knot of Stars at the Heart of the Galaxy
Hans-Walter Rix, Vedant Chandra, Gail Zasowski +15
We show with Gaia XP spectroscopy that extremely metal-rich stars in the Milky Way (EMR; ) - but only those - are largely confined to a tight "knot" at the center…
A perspective on the Milky Way Bulge-Bar as seen from the neutron-capture elements Cerium and Neodymium with APOGEE
J. V. Sales-Silva, K. Cunha, V. V. Smith +28
This study probes the chemical abundances of the neutron-capture elements cerium and neodymium in the inner Milky Way from an analysis of a sample of 2000 stars in the Galact…
