Near-Infrared Spectroscopy of Outer Solar System Objects

AST 0098665 campinsdr。Humberto Campins将领导一项为期三年的系统研究，研究半人马座、跨海王星天体（TNOs）和木星家族（JF）不活跃的彗核。他将得到这三种基团的近红外光谱作为旋转相的函数。如果我们要了解这三种原始太阳系天体之间的进化联系，对大量半人马座彗星、TNOs和JF彗星的旋转相位的光谱变化进行适当的研究是必不可少的。坎平斯博士将在亚利桑那州的新6.5米MMT设备上进行观察，这将允许对每个种群的足够多的成员进行详细的观察，以便对它们的特性进行适当的比较。他已经证明了其中一个天体（8405 Asbolus）的光谱变化是旋转相位的函数

AST 0098665CampinsDr. Humberto Campins will lead a systematic three-year study of Centaurs, Transneptunian Objects (TNOs), and inactive nuclei of Jupiter-family (JF) comets. He will obtain near-infrared spectra as a function of rotational phase for members of these three groups. The proper study of the spectral variability with rotational phase in a significant number of Centaurs, TNOs, and JF comets is essential if we are to understand the evolutionary links between these three populations of primitive Solar System objects. Dr. Campins will observe with the new 6.5- meter MMT facility in Arizona, which will allow detailed observations of enough members of each population for a proper comparison of their properties. He has already demonstrated that one of these objects (8405 Asbolus) has a dramatic spectral variation as a function of rotational phase.***
