Magnetic Field Structure of Orion Source I
Tomoya Hirota, Richard L. Plambeck, Melvyn C. H. Wright +6
We observed polarization of the SiO rotational transitions from Orion Source I (SrcI) to probe the magnetic field in bipolar outflows from this high mass protostar. Both 43 GHz …
Multiple outflows in the high-mass cluster forming region, G25.82-0.17
Jungha Kim, Mi Kyoung Kim, Tomoya Hirota +14
We present results of continuum and spectral line observations with ALMA and 22 GHz water (HO) maser observations using KaVA and VERA toward a high-mass star-forming region, G2…
The First VERA Astrometry Catalog
VERA collaboration, Tomoya Hirota, Takumi Nagayama +59
We present the first astrometry catalog from the Japanese VLBI (very long baseline interferometer) project VERA (VLBI Exploration of Radio Astrometry). We have compiled all the ast…
Extremely high excitation SiO lines in disk-outflow system in Orion Source I
Mi Kyoung Kim, Tomoya Hirota, Masahiro N. Machida +4
We present high-resolution images of the submillimeter SiO line emissions of a massive young stellar object Orion Source I using the Atacama Large Millimeter/ Submillimeter Array (…
Disk-Driven Rotating Bipolar Outflow in Orion Source I
Tomoya Hirota, Masahiro N. Machida, Yuko Matsushita +5
One of the outstanding problems in star-formation theory concerns the transfer of angular momentum such that mass can accrete onto a newly born young stellar object (YSO). From a t…
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…
