本文报道了IRAS-Araki-Alcock 1983 d彗星在12 - 100微米红外波段的观测结果。在红外线中看到的主要特征是一个广泛的尘埃尾巴,在视觉观测中没有报道。粉尘产生率为200 kg/s。远红外光谱表明,平均晶粒的半径沿尾部沿着从30微米减小到5微米。
Observations of comet IRAS-Araki-Alcock 1983d in the infrared region from 12 to 100 microns are reported. The dominant feature seen in the infrared is an extensive dust tail not reported in visual observations. A dust production rate of 200 kg/s is deduced. The far-infrared spectrum suggests that the radius of a mean grain decreases from 30 to 5 microns along the tail.
