NSF/AFOSR Astronomy: Imaging Studies of the Transient Atmospheres of Jupiter's Moons

摘要本研究将使用美国空军的先进光电系统（AEOS）及其可操作的自适应光学系统来获取木卫一和木卫二大气中钾元素的高分辨率图像。这项工作将为钾的来源和汇提供分析和观测验证。在自适应光学系统的基础上，采用日冕光学系统可以提高望远镜系统的散射光性能。自适应光学将使卫星图像锐化，在主焦平面上使用掩星盘来减少卫星表面的明亮图像，以在寒冷的黑暗空间背景下对卫星大气进行成像。该仪器将采用最近开发的用于探测行星大气中的气体的创新图像切片机

Mendillo0088340AbstractThis research will use the Advanced Electro-Optical System (AEOS) of the Air Force with its operational adaptive optics to obtain high-resolution images of the potassium in the atmospheres of Io and Europa. This work will provide an analysis and observational verification for the sources and the sinks of potassium. The scattered light performance of the telescope system will be improved by using coronagraphic optics in addition to the adaptive optics. The adaptive optics will sharpen up the satellite images and an occulting disk will be used at the primary focal plane to reduce the bright image of the satellite surface to image the satellite atmosphere against the cold dark space background. The instrument will employ an innovative image slicer recently developed to detect gases in planetary atmospheres.***
