Insights into the Formation and Evolution History of the Galactic Disk System
Doo Ri Han, Young Sun Lee, Young Kwang Kim +1
We present a kinematic analysis of a sample of 23,908 G- and K-type dwarfs in the Galactic disk. Based on the -abundance ratio, [/Fe], we separated our sample into low- th…
Chemical Cartography. II. The Assembly History of the Galactic Stellar Halo Traced by Carbon-Enhanced Metal-Poor Stars
Young Sun Lee, Timothy C. Beers, Young Kwang Kim
We present an analysis of the kinematic properties of stellar populations in the Galactic halo, making use of over 100,000 main sequence turnoff (MSTO) stars observed in the Sloan…
Dependence of Galactic Halo Kinematics on the Adopted Galactic Potential
Young Kwang Kim, Young Sun Lee, Timothy C. Beers
We explore differences in Galactic halo kinematic properties derived from two commonly employed Galactic potentials: the Stckel potential and the default Milky Way-like p…
Origin and Status of Low-Mass Candidate Hypervelocity Stars
Bum-Suk Yeom, Young Sun Lee, Jae-Rim Koo +2
We present an analysis of the chemical abundances and kinematics of six low-mass dwarf stars, previously claimed to be candidate hypervelocity stars (HVSs). We obtained moderate-re…
Chemical Cartography. I. A Carbonicity Map of the Galactic Halo
Young Sun Lee, Timothy C. Beers, Young Kwang Kim +5
We present the first map of carbonicity, [C/Fe], for the halo system of the Milky Way, based on a sample of over 100,000 main-sequence turnoff stars with available spectroscopy fro…
