Morpho-Kinematic Properties of the 21-Micron Source IRAS 07134+1005
Jun-ichi Nakashima, Nico Koning, Sun Kwok +1
We report the results of a Submillimeter Array (SMA) interferometric observation of 21-micron source IRAS 07134+1005 in the CO J=3-2 line. In order to determine the morpho-kinemati…
First detection of CO lines in a water fountain star
J. H. He, H. Imai, T. I. Hasegawa +2
[Context] Water fountain stars are very young post-AGB stars with high velocity water maser jets. They are the best objects to study the onset of bipolar jets from evolved stars du…
Molecular Line Observations of the SiO Maser Source IRAS 19312+1950
Jun-ichi Nakashima, Shuji Deguchi, Hiroshi Imai +1
IRAS 19312+1950 is a unique SiO maser source, exhibiting a rich set of molecular radio lines, although SiO maser sources are usually identified as oxygen-rich evolved stars, in whi…
Submillimeter Array Observation of the Proto-Planetary Nebula CRL 618 in the CO J=6-5 Line
Jun-ichi Nakashima, David Fong, Tatsuhiko Hasegawa +6
We report on the results of a Submillimeter Array interferometric observation of the proto-planetary nebula CRL 618 in the 12CO J=6-5 line. With the new capability of SMA enabling…
Correlation between Infrared Colors and Intensity Ratios of SiO Maser Lines
Jun-ichi Nakashima, Shuji Deguchi
We present the results of SiO millimeter-line observations of a sample of known SiO maser sources covering a wide dust-temperature range. A cold part of the sample was selected fro…
Identification of Very Red Counterparts of SiO Maser and OH/IR Objects in the GLIMPSE Survey
S. Deguchi, J. Nakashima, S. Kwok +1
Using the 3.6/4.5/5.8/8.0 micron images with 1.2 arcsec pixel resolution from the Spitzer/GLIMPSE survey, we investigated 23 masing and 18 very red objects that were not identified…
