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…
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…
Near-infrared polarimetric study of the bipolar nebula IRAS 19312+1950
K. Murakawa, J. Nakashima, K. Ohnaka +1
We obtained H-band polarimetric data of IRAS 19312+1950 using the near-infrared camera (CIAO) on the 8 m Subaru telescope. In order to investigate the physical properties of the ce…
SiO maser observations of a wide dust-temperature range sample
Jun-ichi Nakashima, Shuji Deguchi
We present the results of SiO line observations of a sample of known SiO maser sources covering a wide dust-temperature range. The aim of the present research is to investigate the…
Detection of HCO+ Emission toward the Planetary Nebula K 3-35
D. Tafoya, Y. Gomez, G. Anglada +8
We report the detection, for the first time, of HCO+ (J=1-0) emission as well as marginal CO (J=1-0) emission toward the planetary nebula (PN) K3-35 as a result of a molecular surv…
