HR-GO II: chemical abundances of low- retrograde dynamically-tagged-groups: Revealing Thamnos as a very metal-poor substructure
Renjing Xie, Zhen Yuan, Haining Li +12
Milky Way halo substructures identified in dynamical space are known to suffer from contamination from the Milky Way in-situ stars, which makes their accreted origins uncertain. We…
Can supernova from runaway stars mimic the signs of absorbing `super-virial' gas?
Mukesh Singh Bisht, Projjwal Banerjee, Biman B. Nath +1
The recent detection of large column density absorption lines from highly ionized gas in a few directions through the circumgalactic medium (CGM) of the Milky Way (MW) has been puz…
Constraints on -process Nucleosynthesis from I and Cm in the Early Solar System
Projjwal Banerjee, Meng-Ru Wu, Jeena S. K
GW170817 has confirmed binary neutron star mergers as one of the sites for rapid neutron capture () process. However, there are large theoretical and experimental uncertainties…
Neutron Star Mergers as the Main Source of R-process: Natal Kicks And Inside-Out Evolution to The Rescue
Projjwal Banerjee, Meng-Ru Wu, Zhen Yuan
Binary neutron star mergers (BNSMs) is currently the most promising source of \textsl{r}-process thanks to the detection of GW170817. The estimated occurring frequency and the amou…
Dynamical Relics of the Ancient Galactic Halo
Zhen Yuan, G. C. Myeong, Timothy C. Beers +11
We search for dynamical substructures in the LAMOST DR3 very metal-poor (VMP) star catalog. After cross-matching with Gaia DR2, there are 3300 VMP stars with available high-quality…
StarGO: A New Method to Identify the Galactic Origins of Halo Stars
Zhen Yuan, Jiang Chang, Projjwal Banerjee +3
We develop a new method StarGO (Stars' Galactic Origin) to identify the galactic origins of halo stars using their kinematics. Our method is based on self-organizing map (SOM), whi…
