Chemical Abundances of the Outer Halo Stars in the Milky Way
M. Ishigaki, M. Chiba, W. Aoki
We present chemical abundances of 57 metal-poor stars that are likely constituents of the outer stellar halo in the Milky Way. Almost all of the sample stars have an orbit reaching…
6Li/7Li estimates for metal-poor stars
A. E. Garcia Perez, W. Aoki, S. Inoue +3
The presence of the lithium-6 isotope in some metal-poor stars is a matter of surprise because of the high values observed. Non-standard models of Big Bang nucleosynthesis and pre-…
Integral Field Spectroscopy of the Quadruply Lensed Quasar 1RXS J1131-1231: New Light on Lens Substructures
H. Sugai, A. Kawai, A. Shimono +5
We have observed the quadruply lensed quasar 1RXS J1131-1231 with the integral field spectrograph mode of the Kyoto Tridimensional Spectrograph II mounted on the Subaru telescope.…
The Surprisingly Steep Mass Profile of Abell 1689, from a Lensing Analysis of Subaru Images
Tom Broadhurst, Masahiro Takada, Keiichi Umetsu +4
Subaru observations of A1689 (z=0.183) are used to derive an accurate, model-independent mass profile for the entire cluster, r<2 Mpc/h, by combining magnification bias and distort…
Formation of giant globular cluster G1 and the origin of the M31 stellar halo
Kenji Bekki, Masashi Chiba
We first demonstrate that globular cluster G1 could have been formed by tidal interaction between M31 and a nucleated dwarf galaxy (dE,N). Our fully self-consistent numerical simul…
