Discovery of Infalling Motion with Rotation of the Cluster-Forming Clump S235AB and Its Implication to the Clump Structures
Tomomi Shimoikura, Kazuhito Dobashi, Tomoaki Matsumoto +1
We report the discovery of infalling motion with rotation of S235AB the massive cluster-forming clump (~10^3 Mo) in the S235 region. Our C18O observations with the 45m telescope at…
Revealing the physical properties of molecular gas in Orion with a large scale survey in J=2-1 lines of 12CO, 13CO and C18O
Atsushi Nishimura, Kazuki Tokuda, Kimihiro Kimura +8
We present fully sampled ~3' resolution images of the 12CO(J=2-1), 13CO(J=2-1), and C18O(J=2-1) emission taken with the newly developed 1.85-m mm-submm telescope toward the entire…
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…
Colliding Filaments and a Massive Dense Core in the Cygnus OB 7 Molecular Cloud
Kazuhito Dobashi, Tomoaki Matsumoto, Tomomi Shimoikura +4
We report results of molecular line observations carried out toward a massive dense core in the Cyg OB 7 molecular cloud. The core has an extraordinarily large mass ($\sim1.1 \time…
Cluster Formation Triggered by Filament Collisions in Serpens South
Fumitaka Nakamura, Koji Sugitani, Tomohiro Tanaka +24
The Serpens South infrared dark cloud consists of several filamentary ridges, some of which fragment into dense clumps. On the basis of CCS (), HCN (), N$_2…
High abundance ratio of CO to CO toward photon-dominated regions in the Orion-A giant molecular cloud
Yoshito Shimajiri, Yoshimi Kitamura, Masao Saito +11
Aims. We derive physical properties such as the optical depths and the column densities of CO and CO to investigate the relationship between the far ultraviolet (FUV)…
