（379）Huenna及其卫星的光谱比较
A spectral comparison of (379) Huenna and its satellite
摘要：
利用NASA IRTF上的SpeX技术对忒弥斯家族小行星（379）Huenna（D~98 km）及其6 km卫星进行了近红外光谱测量。在观测时，伴星距离主星超过1.5”，并且大约暗5等。我们描述了一种方法，用于分离和提取的信号的伴侣小行星时，信号是不完全解决的主要。（379）Huenna的光谱在1 μm附近有一个宽而浅的特征，斜率很低，是C型小行星的特征。次级的光谱与C-复合体或X-复合体的分类学分类一致。数据的质量不足以识别次级光谱中的任何细微特征。
英文摘要：
We present near-infrared spectral measurements of Themis family asteroid (379) Huenna (D~98 km) and its 6 km satellite using SpeX on the NASA IRTF. The companion was farther than 1.5" from the primary at the time of observations and was approximately 5 magnitudes dimmer. We describe a method for separating and extracting the signal of a companion asteroid when the signal is not entirely resolved from the primary. The spectrum of (379) Huenna has a broad, shallow feature near 1 μm and a low slope, characteristic of C-type asteroids. The secondary's spectrum is consistent with the taxonomic classification of C-complex or X-complex. The quality of the data was not sufficient to identify any subtle feature in the secondary's spectrum.
