ALMA imaging study of methyl formate (HCOOCH) in the torsionally excited states towards Orion KL
Yusuke Sakai, Kaori Kobayashi, Tomoya Hirota
We recently reported the first identification of rotational transitions of methyl formate (HCOOCH) in the second torsionally excited state toward Orion Kleinmann-Low (KL) obs…
ALMA Observations of the IRDC Clump G34.43+00.24 MM3: DNC/HNC Ratio
Takeshi Sakai, Nami Sakai, Kenji Furuya +6
We have observed the clump G34.43+00.24 MM3 associated with an infrared dark cloud in DNC =3--2, HNC =3--2, and NH =3--2 with the Atacama Large Millimeter/s…
Accelerating a water maser face-on jet from a high mass young stellar object
Kazuhito Motogi, Kazuo Sorai, Mareki Honma +6
We report on a long-term single-dish and VLBI monitoring for intermittent flare activities of a Dominant Blue-Shifted HO Maser (DBSM) associated with a southern high mass you…
ALMA Imaging of Millimeter/Submillimeter Continuum Emission in Orion KL
Tomoya Hirota, Mi Kyoung Kim, Yasutaka Kurono +1
We have carried out high resolution observations with Atacama Large Millimeter/Submillimeter Array (ALMA) of continuum emission from Orion KL region. We identify 11 compact sources…
