Methanol Observation of IRAS 19312+1950: A Possible New Type of Class I Methanol Masers
Jun-ichi Nakashima, Andrej M. Sobolev, Svetlana V. Salii +3
We report the result of a systematic methanol observation toward IRAS 19312+1950. The properties of the SiO, H2O and OH masers of this object are consistent with those of mass-losi…
The spatiokinematical structure of H_2O and OH masers in the "water fountain" source IRAS 18460-0151
Hiroshi Imai, Shuji Deguchi, Jun-ichi Nakashima +2
Using the Very Long Baseline Array and the European VLBI Network, we have observed 22.2 GHz H_2O and 1612 MHz OH masers in the "water fountain" source IRAS 18460-0151. The H_2O mas…
Water Maser Survey on AKARI and IRAS Sources: A Search for "Low-Velocity" Water Fountains
Bosco Yung, Jun-ichi Nakashima, Hiroshi Imai +3
We present the results of a 22GHz H2O maser survey toward a new sample of AGB and post-AGB star candidates. Most of the objects are selected for the first time based on the AKARI d…
Pilot VLBI Survey of SiO v=3 J=1--0 Maser Emission around Evolved Stars
Hiroshi Imai, Miyako Oyadomari, Sze Ning Chong +9
In this Letter, we report detections of SiO v=3 J=1--0 maser emission in very long baseline interferometric (VLBI) observations towards 4 out of 12 long-period variable stars: WX P…
Maser Observations of Westerlund 1 and Comprehensive Considerations on Maser Properties of Red Supergiants Associated with Massive Clusters
Thomas K. T. Fok, Jun-ichi Nakashima, Bosco H. K. Yung +2
We report the results of Australia Telescope Compact Array (ATCA) observations of the Westerlund~1 (Wd1) region in the SiO v=1, J=1-0 and H2O 6(16)-5(23) maser lines, and we also r…
Extremely Strong ^{13}CO J=3-2 Line in the "Water Fountain" IRAS 16342-3814: Evidence for the Hot-Bottom Burning
Hiroshi Imai, Sze-Ning Chong, Jin-Hua He +5
We observed four "water fountain" sources in the CO J=3-2 line emission with the Atacama Submillimeter Telescope Experiment (ASTE) 10 m telescope in 2010-2011. The water fountain s…
