| 内容記述 | The observations of the M giant star, IRAS 09371+1212, in the 40 to 70 microns emission bands, are reported. This star has a circumstellar CO envelope, and a unique infrared color, attributed to ice emission bands. The observations performed in February 1988, using grating spectrometer, showed that the far infrared bands of ice are the strongest known in the sky, and that its dust temperature (50K) is the lowest known for a circumstellar envelope. The 43 microns band of ice is also detected in several very cold circumstellar envelopes. |
