Stellar Metallicities from DECam -band Photometry: A Study of Milky Way Ultra-Faint Dwarf Galaxies
Yue Pan, Anirudh Chiti, Alex Drlica-Wagner +5
We conducted an in-depth analysis of candidate member stars located in the peripheries of three ultra-faint dwarf (UFD) galaxy satellites of the Milky Way: Boötes I (Boo1), Boötes…
Signatures of tidal disruption of the Hercules ultra-faint dwarf galaxy
Xiaowei Ou, Anirudh Chiti, Nora Shipp +6
The Hercules ultra-faint dwarf galaxy (UFD) has long been hypothesized to be tidally disrupting, yet no conclusive evidence has been found for tidal disruption owing partly to diff…
A Strontium-rich Ultra Metal-poor Star in the Atari Disk Component
Mohammad K. Mardini, Anna Frebel, Anirudh Chiti
We report on the discovery of the first ultra metal-poor (UMP) star 2MASS~J205001946613298 (J20506613; \mbox{[Fe/H] = }) selected from the Gaia BP/RP spectral catalog…
Enrichment by Extragalactic First Stars in the Large Magellanic Cloud
Anirudh Chiti, Mohammad Mardini, Guilherme Limberg +8
The Large Magellanic Cloud (LMC) is the Milky Way's most massive satellite galaxy, which only recently (~2 billion years ago) fell into our Galaxy. Since stellar atmospheres preser…
Reading Between the (Spectral) Lines: Magellan/IMACS spectroscopy of the Ultra-faint Dwarf Galaxies Eridanus IV and Centaurus I
M. E. Heiger, T. S. Li, A. B. Pace +17
We present a spectroscopic analysis of Eridanus IV (Eri IV) and Centaurus I (Cen I), two ultra-faint dwarf galaxies of the Milky Way. Using IMACS/Magellan spectroscopy, we identify…
Strong Variability in AzV 493, an Extreme Oe-Type Star in the SMC
M. S. Oey, N. Castro, M. Renzo +11
We present 18 years of OGLE photometry together with spectra obtained over 12 years, revealing that the early Oe star AzV 493 shows strong photometric (Delta I < 1.2 mag) and spect…
