Rotation-Resolved Spectroscopy of a Very Young Asteroid, (1270) Datura
Naruhisa Takato
(1270) Datura is the largest member of a very young asteroid cluster that was thought to be broken-up 0.45 Myr ago. The light-curve and the rotation-resolved reflectance spectra (0…
Diffraction-limited 3 um Spectroscopy of IRAS 04296+3429 and IRAS 05341+0852: Spatial Extent of Hydrocarbon Dust Emission and Dust Evolutionary Sequence
M. Goto, Sun Kwok, H. Takami +15
We present 3 um spectroscopy of the carbon-rich proto-planetary nebulae IRAS 04296+3429 and IRAS 05341+0852 conducted with the adaptive optics system at the Subaru Telescope. We ut…
Adaptive Optics Spectroscopy of the [Fe II] Outflows from HL Tauri and RW Aurigae
Tae-Soo Pyo, Masahiko Hayashi, Naoto Kobayashi +16
We present new results of [Fe II] 1.644-micron spectroscopy toward the jets from HL Tau and RW Aur carried out with the Subaru Telescope combined with the adaptive optics system. W…
First Detection of NaI D lines in High-Redshift Damped Lyman-alpha Systems
Sohei Kondo, Naoto Kobayashi, Yosuke Minowa +15
A Near-infrared (1.18-1.35 micron) high-resolution spectrum of the gravitationally-lensed QSO APM 08279+5255 was obtained with the IRCS mounted on the Subaru Telescope using the AO…
A Young Brown Dwarf Companion to DH Tauri
Yoichi Itoh, Masahiko Hayashi, Motohide Tamura +20
We present the detection of a young brown dwarf companion DH Tau B associated with the classical T Tauri star DH Tau. Near-infrared coronagraphic observations with CIAO on the Suba…
H Emission Nebulosity Associated with KH 15D
A. T. Tokunaga, S. Dahm, W. Gaessler +14
An H emission filament is found in close proximity to the unique object KH 15D using the adaptive optics system of the Subaru Telescope. The morphology of the filament, the pre…
