Tracing Back a Second-generation Star Stripped from Terzan 5 by the Galactic Bar

The Astrophysical Journal Letters
The Galactic bulge hosts the Milky Way’s oldest stars, possibly coming from disrupted globular clusters (GCs) or the bulge’s primordial building blocks, making these stars witnesses to the Galaxy’s early chemical enrichment.

RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99

The Astrophysical Journal Letters
Patchick 99 is a candidate globular cluster located in the direction of the Galactic bulge, with a proper motion almost identical to the field and extreme field star contamination. A recent analysis suggests it is a low-luminosity globular cluster with a

Composition of Giants 1° North of the Galactic Center: Detailed Abundance Trends for 21 Elements Observed with IGRINS

The Astrophysical Journal
We report the first high-resolution, detailed abundances of 21 elements for giants in the Galactic bulge/bar within 1° of the Galactic plane, where high extinction has rendered such studies challenging. Our high-signal-to-noise-ratio and high-resolution,

Shiva and Shakti: Presumed Proto-Galactic Fragments in the Inner Milky Way

The Astrophysical Journal
Using Gaia Data Release 3 astrometry and spectroscopy, we study two new substructures in the orbit–metallicity space of the inner Milky Way: Shakti and Shiva.
