NEAR-IR Spectroscopy of Young Stars in the Braid Nebula Star Formation Region in Cygnus Ob7
Colin Aspin, Tracy L. Beck, Tae-Soo Pyo +8
We present 1.4 to 2.5 um integral field spectroscopy of 16 stars in the Braid Nebula star formation region in Cygnus OB7. These data forms one aspect of a large-scale multi-wavelen…
GRB 080913 at redshift 6.7
J. Greiner, T. Kruehler, J. P. U. Fynbo +44
We report on the detection by Swift of GRB 080913, and subsequent optical/near-infrared follow-up observations by GROND which led to the discovery of its optical/NIR afterglow and…
Spatially Resolved Molecular Hydrogen Emission in the Inner 200AU Environments of Classical T Tauri Stars
Tracy L. Beck, Peter J. McGregor, Michihiro Takami +1
We present 2.0-2.4micron integral field spectroscopy at adaptive optics spatial resolution (~0.''1) obtained with the Near-infrared Integral Field Spectrograph (NIFS) at Gemini Nor…
A Micro Molecular Bipolar Outflow From HL Tau
Michihiro Takami, Tracy L. Beck, Tae-Soo Pyo +2
We present detailed geometry and kinematics of the inner outflow toward HL Tau observed using Near Infrared Integral Field Spectograph (NIFS) at the Gemini-North 8-m Observatory. W…
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,…
SUBARU HDS Observations of a Balmer-Dominated Shock in Tycho's Supernova Remnant
Jae-Joon Lee, Bon-Chul Koo, John Raymond +4
We present an Ha spectral observation of a Balmer-dominated shock on the eastern side of Tycho's supernova remnant using the Subaru Telescope. Utilizing the High Dispersion Spectro…
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…
Variability of the NGC 1333 IRAS 4A Outflow: Molecular Hydrogen and Silicon Monoxide Images
Minho Choi, Klaus W. Hodapp, Masahiko Hayashi +3
The NGC 1333 region was observed in the H2 1-0 S(1) line. The H2 images cover a 5' x 7' region around IRAS 4. Numerous H2 emission features were detected. The northeast-southwest b…
Kinematics of SiO J=8-7 Emission towards the HH 212 Jet
Michihiro Takami, Shigehisa Takamuwa, Munetake Momose +5
We present SiO J=8-7 (347.3 GHz) observations towards HH 212 using the ASTE telescope. Our observations with a 22''-diameter beam show that the SiO emission is highly concentrated…
