摘要:

我们目前的可见光和近红外反射光谱和解释小行星10537(1991 RY 16)的表面矿物学。这个天体的光谱在主带小行星中是没有先例的。一个以0.63微米为中心的独特吸收带可以归因于几种矿物之一。明显的1-和2-微米吸收带表明,10537的组成是辉石和橄榄石的混合物,它起源于部分或完全分化的母体。最接近的类似物是主带小行星349 Dembowska,但10537可能是一个完全侵蚀的母体的孤立碎片。

英文摘要:

We present visible and near-infrared reflectance spectra and interpreted surface mineralogy for asteroid 10537 (1991 RY16). The spectrum of this object is without precedent amongst the Main Belt asteroids. A unique absorption band centered at 0.63 microns could be attributed to one of several mineralogies. Pronounced 1- and 2-micron absorption bands suggest that the composition of 10537 is a mixture of pyroxenes and olivine and that it originated from a parent body that was partially or fully differentiated. The closest available analog is the large Main Belt asteroid 349 Dembowska but 10537 may be an isolated fragment from a completely eroded parent body.
