Cosmological insights into the early accretion of r-process-enhanced stars II. Dynamical identification of lost members of Reticulum II
P. Berczik, M. Ishchenko, O. Sobodar +1
Aims. We identify the possible dynamical connection between individual r-process-enhanced stars and the ultra-faint dwarf galaxy Reticulum II based on the current phase-space infor…
The oldest stars with low neutron-capture element abundances and origins in ancient dwarf galaxies
Hillary Diane Andales, Ananda Santos Figueiredo, Casey Gordon Fienberg +2
We present a detailed chemical abundance and kinematic analysis of six extremely metal-poor ( [Fe/H] 2.9) halo stars with very low neutron-capture abundances ([Sr…
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…
Unraveling the Origins and Development of the Galactic Disk through Metal-Poor Stars
Maria Rah, Manolya Yatman, Ali Taani +2
The Milky Way is a spiral galaxy comprising three main components: the Bulge, the Disk, and the Halo. Of particular interest is the Galactic disk, which holds a significant portion…
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…
