Carbon-Chain and Organic Molecules around Very Low-Luminosity Protostellar Objects of L1521F-IRS and IRAM 04191+1522
Shigehisa Takakuwa, Nagayoshi Ohashi, Yuri Aikawa
We have observed dense gas around the Very Low-Luminosity Ob jects (VeLLOs) L1521F-IRS and IRAM 04191+1522 in carbon-chain and organic molecular lines with the Nobeyama 45 m telesc…
New Panoramic View of CO and 1.1 mm Continuum Emission in the Orion A Molecular Cloud. I. Survey Overview and Possible External Triggers of Star Formation
Yoshito Shimajiri, Ryohei Kawabe, Shigehisa Takakuwa +17
We present new, wide and deep images in the 1.1 mm continuum and the CO (=1-0) emission toward the northern part of the Orion A Giant Molecular Cloud (Orion-A GMC). The 1…
Outflow - Core Interaction in Barnard 1
Masaaki Hiramatsu, Naomi Hirano, Shigehisa Takakuwa
In order to study how outflows from protostars influence the physical and chemical conditions of the parent molecular cloud, we have observed Barnard 1 (B1) main core, which harbor…
High-Velocity Jets and Slowly Rotating Envelope in B335
Hsi-Wei Yen, Shigehisa Takakuwa, Nagayoshi Ohashi
We have performed detailed imaging and analyses of SMA observations in 230 GHz continuum, 12CO (2-1), 13CO (2-1), and C18O (2-1) emission toward B335, a Bok globule with an embedde…
