Diffraction-limited 3 µm spectroscopy of IRAS 04296+3429 and IRAS 05341+0852: spatial extent of hydrocarbon dust emission and dust evolutionary sequence (2007)

Goto, Miwa, Kwok, Sun, Takami, Hideki, Hayashi, Masa, Gaessler, W., Hayano, Yutaka, ...

We present 3 mum spectroscopy of the carbon-rich protoplanetary nebulae IRAS 04296+3429 and IRAS 05341+0852, conducted with the adaptive optics system at the Subaru Telescope. We utilize the nearly...

Kinematics of SiO J=8-7 Emission towards the HH 212 Jet (2006)

Takami, Michihiro, Takamuwa, Shigehisa, Momose, Munetake, Hayashi, Masa, Davis, Christopher, Pyo, Tae-Soo, ...

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 within 1' of the...

Carbon isotope ratio in 12CO/13CO toward local molecular clouds with near-infrared high-resolution spectroscopy of vibrational transition bands (2003)

Goto, Miwa, Usuda, Tomonori, Takato, Naruhisa, Hayashi, Masa, Sakamoto, Seiichi, Gaessler, W., ...

We report the carbon monoxide isotope ratio in local molecular clouds toward LkH**alpha; 101, AFGL 490, and Mon R2 IRS 3. The vibrational transition bands of 12CO **nu;=2**lt;--0 and 13CO...
