A molecular line survey of the extreme carbon star CRL 3068 at millimeter wavelengths
Yong Zhang, Sun Kwok, Jun-ichi Nakashima
We present the results of a molecular line survey of the extreme carbon star CRL 3068. The observations were carried out with the Arizona Radio Observatory (ARO) 12m telescope and…
CO in OH/IR stars close to the Galactic centre
A. Winnberg, S. Deguchi, M. J. Reid +3
Aims: A pilot project has been carried out to measure circumstellar CO emission from three OH/IR stars close to the Galactic centre. The intention was to find out whether it would…
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…
