我们提出了光谱和几何反照率的目录，代表不同类型的太阳系天体，从 0.45 到 2.5μm。我们分析了已发布的太阳系天体的校准、未校准光谱和反照率，并得出了代表太阳系天体多样性的 19 个天体的一组参考光谱和参考反照率。我们还发现之前发布的数据似乎受到污染。我们的目录提供了将系外行星观测结果与我们太阳系中 19 个天体进行比较的基线，这可以帮助确定系外行星的优先顺序，以便利用下一代极大望远镜和天基直接观测任务进行时间密集的后续行动。利用这些太阳系天体的高分辨率和低分辨率光谱，我们还得出这些天体的颜色，并探索如何使用颜色-颜色图来初步区分岩石、冰和气态系外行星。我们探索太阳系模拟天体绕不同主恒星运行时颜色如何变化。该太阳系参考光谱和反照率目录可通过卡尔萨根研究所下载。
We present a catalog of spectra and geometric albedos, representative of the different types of solar system bodies, from 0.45 to 2.5 μm. We analyzed published calibrated, uncalibrated spectra, and albedos for solar system objects and derived a set of reference spectra and reference albedos for 19 objects that are representative of the diversity of bodies in our solar system. We also identified previously published data that appear contaminated. Our catalog provides a baseline for comparison of exoplanet observations to 19 bodies in our own solar system, which can assist in the prioritization of exoplanets for time intensive follow-up with next-generation extremely large telescopes and space-based direct observation missions. Using high- and low-resolution spectra of these solar system objects, we also derive colors for these bodies and explore how a color-color diagram could be used to initially distinguish between rocky, icy, and gaseous exoplanets. We explore how the colors of solar system analog bodies would change when orbiting different host stars. This catalog of solar system reference spectra and albedos is available for download through the Carl Sagan Institute.
