SUBARU Near-Infrared Multi-Color Images of Class II Young Stellar Object, RNO91
Satoshi Mayama, Motohide Tamura, Masahiko Hayashi +6
We conducted sub-arcsecond near-infrared imaging observations of RNO91 with CIAO mounted on the SUBARU 8.2 m telescope. We present our JHK band data along with optical images, whic…
Near-Infrared Coronagraphic Observations of the T Tauri Binary System UY Aur
Tomonori Hioki, Yoichi Itoh, Yumiko Oasa +10
We present a near-infrared image of UY Aur, a 0.9" separated binary system, using the Coronagraphic Imager with Adaptive Optics on the Subaru Telescope. Thanks to adaptive optics,…
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…
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…
Current Performance and On-Going Improvements of the 8.2 m Subaru Telescope
Masanori Iye, Hiroshi Karoji, Hiroyasu Ando +2
An overview of the current status of the 8.2 m Subaru Telescope constructed and operated at Mauna Kea, Hawaii, by the National Astronomical Observatory of Japan is presented. The b…
High resolution imaging polarimetry of HL Tau and magnetic field structure
P. W. Lucas, Misato Fukagawa, Motohide Tamura +10
We present high quality near infrared imaging polarimetry of HL Tau at 0.4 to 0.6 arcsec resolution, obtained with Subaru/CIAO and UKIRT/IRCAM. 3-D Monte Carlo modelling with align…
