Trigonometric Parallax of IRAS 22555+6213 with VERA: 3-Dimensional View of Sources Along the Same Line of Sight
James O. Chibueze, Hirofumi Sakanoue, Takumi Nagayama +11
We report the results of the measurement of the trigonometric parallax of an HO maser source in \r22 with the VLBI Exploration of Radio Astrometry (VERA). The annual parallax w…
Observations of 6.7 GHz Methanol Masers with EAVN I: VLBI Images of the first Epoch of Observations
Kenta Fujisawa, Koichiro Sugiyama, Kazuhito Motogi +26
Very long baseline interferometry (VLBI) monitoring of the 6.7 GHz methanol maser allows us to measure the internal proper motions of the maser spots and therefore study the gas mo…
Intermittent maser flare around the high mass young stellar object G353.273+0.641 II: Detection of a radio and molecular jet
Kazuhito Motogi, Kazuo Sorai, Kotaro Niinuma +3
We report the first detection of a radio-continuum and molecular jet associated with a dominant blue-shifted maser source, G353.273+0.641. A radio jet is extended 3000 au along NW-…
VLBI Astrometry of the Semiregular Variable RX Bootis
Tatsuya Kamezaki, Akiharu Nakagawa, Toshihiro Omodaka +10
We present distance measurement of the semiregular variable RX Bootis (RX Boo) with its annual parallax. Using the unique dual-beam system of the VLBI Exploration of Radio Astromet…
Bursting Activity in a High-Mass Star-Forming Region G33.64-0.21 Observed with the 6.7 GHz Methanol Maser
Kenta Fujisawa, Koichiro Sugiyama, Nozomu Aoki +9
We report the detection of bursts of 6.7 GHz methanol maser emission in a high-mass star-forming region, G33.64-0.21. One of the spectral components of the maser in this source cha…
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…
