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…
Disk-Like Structure in the Semi-Regular Pulsating Star, X Her
Jun-ichi Nakashima
The author reports a result of an interferometric observation of the semiragular pulsating star with an unusual narrow molecular line profile, X Her, in the CO J=1-0 line with the…
Study of the Bipolar Nebula IRAS 19312+1950. II. Circumstellar Chemistry
S. Deguchi, J. Nakashima, S. Takano
The bipolar nebula, IRAS 19312+1950, is a unique SiO maser source exhibiting both properties as young and evolved objects. To clarify the nature of this object, we made molecular l…
Study of the Bipolar Nebula IRAS 19312+1950. I. Mapping Observations
J. Nakashima, S. Deguchi, N. Kuno
IRAS 19312+1950 is an SiO maser source that exhibits a prominent bipolar nebulosity. Mapping observations of this object were made in the CO J=1--0, 13CO J=1--0, C18O J=1--0, CS J=…
