Abstract

We consider prospects for investigating asteroids with the multicolor photometric method at the Robophot telescope—a robotic telescope of the Dall–Kirkham system with a 0.6-m primary mirror and a focal length of 4.2 m. It is equipped with a three-channel photometer with the g', r', and i' filters of the SDSS photometric system, and the field of view is 20′. The use of a three-channel photometer in observations of small bodies will make it possible to construct multicolor light curves without phase delays. Diagrams of the r' – i' and g' – r' color indices will provide the means of classifying the C- and S-type asteroids. From the high-accuracy light curves, the rotation parameters of asteroids can be determined, for which it is necessary to take the Yarkovsky effect into account correctly. The results of multicolor photometric observations at the Robophot telescope will allow for solving complex scientific problems related to the studies of the physical and dynamic evolution of small bodies in the Solar System.

太阳系小天体的多色光度法:Roboopht望远镜的性能潜力

摘要

我们考虑在Robophot望远镜中使用多色光度法研究小行星的前景,该望远镜是Dall–Kirkham系统的机器人望远镜,具有0.6 m的主镜和4.2 m的焦距。它配备了带有SDSS光度系统的g ' ,r '和i '滤光片的三通道光度计,视场为20'。在观察小物体时使用三通道光度计将可以构建没有相位延迟的多色光曲线。所述的图ř “ -”和' - [R颜色指数将提供对C型和S型小行星进行分类的方法。从高精度的光曲线可以确定小行星的旋转参数,为此必须正确考虑Yarkovsky效应。Robophot望远镜的多色光度学观测结果将解决与研究太阳系小天体的物理和动态演化有关的复杂科学问题。
