Spatially Resolved 3 micron Spectroscopy of Elias 1: Origin of Diamonds in Protoplanetary Disks
M. Goto, Th. Henning, A. Kouchi +8
We present spatially resolved 3 um spectra of Elias 1 obtained with an adaptive optics system. The central part of the disk is almost devoid of PAH emission at 3.3 um; it shows up…
Subaru IR Echelle Spectroscopy of Herbig-Haro Driving Sources I. H_2 and [Fe II] Emission
M. Takami, A. Chrysostomou, T. P. Ray +6
We present infrared echelle spectroscopy of three Herbig-Haro (HH) driving sources (SVS 13, B5-IRS 1 and HH 34 IRS) using Subaru-IRCS. The large diameter of the telescope and wide…
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…
Detection of a warm molecular wind in DG Tauri
M. Takami, A. Chrysostomou, T. P. Ray +5
We detect near-infrared H2 emission in DG Tau using the Infrared Camera and Spectrograph (IRCS) on the 8.2-m SUBARU telescope. The spectra obtained along the jet axis show that the…
Absorption Line Survey of H3+ toward the Galactic Center Sources I. GCS 3-2 and GC IRS3
M. Goto, B. J. McCall, T. R. Geballe +4
We present high-resolution (R = 20000) spectroscopy of H3+ absorption toward the luminous Galactic center sources GCS 3-2 and GC IRS 3. With the efficient wavelength coverage affor…
HeI 1.083 micron emission and absorption in DG Tau: line excitation in jet, hot wind, and accretion flow
M. Takami, A. Chrysostomou, J. Bailey +3
We present long-slit spectroscopy and spectro-astrometry of HeI 1.083 micron emission in the T Tauri star, DG Tau. We identify three components in the HeI feature: (1) a blueshifte…
Infrared Star Count Models and Their Application to the Subaru Deep Field
T. Nakajima, F. Iwamuro, T. Maihara +11
We construct infrared star count models of the Galaxy applicable at faint magnitudes. In addition to dwarfs and subdwarfs, we also take into account L dwarfs, T dwarfs, and white d…
[OII]3727 Emission from the Companion to the Quasar BR 1202-0725 at z=4.7
K. Ohta, T. Matsumoto, T. Maihara +10
Results of a narrow-band imaging for the redshifted [OII]3727 emission around a quasar at z=4.7 obtained with the Subaru telescope and CISCO (a Cassegrain near infrared camera) are…
Near-infrared emission-line galaxies in the Hubble Deep Field North
F. Iwamuro, K. Motohara, T. Maihara +12
We present the 2.12~m narrow-band image of the Hubble Deep Field North taken with the near-infrared camera (CISCO) on the Subaru telescope. Among five targets whose H or [O~{…
Infrared Imaging of the Gravitational Lens PG 1115+080 with the Subaru Telescope
F. Iwamuro, K. Motohara, T. Maihara +8
We present high spatial resolution images of the gravitational-lens system PG 1115+080 taken with the near-infrared camera (CISCO) on the Subaru telescope. The FWHM of the combined…
