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…
Evidence for the accretion origin of halo stars with an extreme r-process enhancement
Qian-Fan Xing, Gang Zhao, Wako Aoki +4
Small stellar systems like dwarf galaxies are suggested to be the main building blocks of our Galaxy by numerical simulations in Lambda CDM models. The existence of star streams li…
Origin of the excess of high-energy retrograde stars in the Galactic halo
Tadafumi Matsuno, Wako Aoki, Takuma Suda
We report on the very low -element abundances of a group of metal-poor stars with high orbital energy and with large retrograde motion in the Milky Way halo, whose excess has be…
