A detailed analysis on the cloud structure and dynamics in Aquila Rift

Tomomi Shimoikura, Kazuhito Dobashi, Yoshiko Hatano +1

We present maps in several molecular emission lines of a 1 square-degree region covering the W40 and Serpens South molecular clouds belonging to the Aquila Rift complex. The observ…

First clear detection of the CCS Zeeman splitting toward the pre-stellar core, Taurus Molecular Cloud-1

Fumitaka Nakamura, Seiji Kameno, Takayoshi Kusune +4

We report a first clear detection of the Zeeman splitting of a CCS emission line at 45 GHz toward a nearby prestellar dense filament, Taurus Molecular Cloud-1. We observed HCN…

Dense Clumps and Candidates for Molecular Outflows in W40

Tomomi Shimoikura, Kazuhito Dobashi, Fumitaka Nakamura +4

We report results of the CO(J=3-2) and HCO+(J=4-3) observations of the W40 HII region with the ASTE 10 m telescope (HPBW~22 arcsec) to search for molecular outflows and dense clump…

Star formation in turbulent molecular clouds with colliding flow

Tomoaki Matsumoto, Kazuhito Dobashi, Tomomi Shimoikura

Using self-gravitational hydrodynamical numerical simulations, we investigated the evolution of high-density turbulent molecular clouds swept by a colliding flow. The interaction o…

Identification of Bursting Water Maser Features in Orion KL

Tomoya Hirota, Masato Tsuboi, Kenta Fujisawa +10

In February 2011, a burst event of the HO maser in Orion KL (Kleinmann-Low object) has started after 13-year silence. This is the third time to detect such phenomena in Orion…
