Detailed CO ( = 1--0, 2--1 and 3--2) observations toward an H{\sc ii} region RCW~32 in the Vela Molecular Ridge
Rei Enokiya, Hidetoshi Sano, Katsuhiro Hayashi +9
We made CO ( = 1--0, 2--1, and 3--2) observations toward an H{\sc ii} region RCW~32 in the Vela Molecular Ridge. The CO gas distribution associated with the H{\sc ii} region was…
A new view of the giant molecular cloud M16 (Eagle Nebula) in 12CO J=1-0 and 2-1 transitions with NANTEN2
Atsushi Nishimura, Jean Costes, Tetsuta Inaba +11
M16, the Eagle Nebula, is an outstanding HII region where extensive high-mass star formation is taking place in the Sagittarius Arm, and hosts the remarkable "pillars" observed wit…
High-mass star formation possibly triggered by cloud-cloud collision in the HII region RCW 34
Katsuhiro Hayashi, Hidetoshi Sano, Rei Enokiya +12
We report a possibility that the high-mass star located in the HII region RCW 34 was formed by a triggering induced by a collision of molecular clouds. Molecular gas distributions…
RCW 36 in the Vela Molecular Ridge: Evidence for a high-mass star cluster formation triggered by Cloud-Cloud Collision
Hidetoshi Sano, Rei Enokiya, Katsuhiro Hayashi +21
A collision between two molecular clouds is one possible candidate for high-mass star formation. The HII region RCW 36, located in the Vela molecular ridge, contains a young star c…
High-mass star formation in Orion possibly triggered by cloud-cloud collision III, NGC2068 and NGC2071
Shinji Fujita, Daichi Tsutsumi, Akio Ohama +12
Using the NANTEN2 Observatory, we carried out a molecular line study of high-mass star forming regions with reflection nebulae, NGC 2068 and NGC 2071, in Orion in the 13CO(J=2-1) t…
