Abstract

The study of the Solar System is fundamental to answer key questions from space agencies, as outlined in their strategic plans, about the content, origin, and evolution of the Solar System and the potential for life elsewhere. The UV spectral range is a crucial window to investigate a large area of phenomena associated with this objective, ranging from the surfaces to the atmospheres and magnetospheres of the Solar System bodies. In this White Paper, submitted to ESA in response to the Voyage 2050 call, we present a few examples of science issues that could be addressed about surfaces, atmospheres, and magnetospheres for different objects in the Solar System using UV observations. After the planned termination of the highly successful Hubble Space Telescope (HST), a new multi-objects UV observatory with UV spectro-imager to map the surfaces, atmospheres, and auroral regions of the different objects of the Solar System, and spectropolarimeter to provide measurements on the surface texture, atmospheric aerosols, surface pressure for KBOs, and magnetic field measurements, would be needed to answer the major questions presented in this paper and to open new possibilities of exploration in the Solar System and beyond.

紫外探测太阳系

对太阳系的研究是回答空间机构提出的关键问题的基础，正如他们在战略计划中概述的那样，关于太阳系的内容、起源和演化以及其他地方存在生命的可能性。紫外光谱范围是研究与该目标相关的大面积现象的关键窗口，范围从太阳系天体的表面到大气和磁层。在这份白皮书中，我们提出了一些科学问题的例子，这些问题可以利用紫外线观测来解决太阳系中不同物体的表面、大气和磁层。在成功的哈勃太空望远镜(HST)计划终止之后，一个新的多目标紫外天文台，用紫外光谱成形仪来绘制太阳系不同物体的表面、大气和极光区域，用分光偏振仪来测量表面纹理、大气气溶胶、柯伊伯带天体的表面压力和磁场测量。将需要回答本文中提出的主要问题，并为探索太阳系和更远的地方开辟新的可能性。

期刊介绍： Many new instruments for observing astronomical objects at a variety of wavelengths have been and are continually being developed. Furthermore, a vast amount of effort is being put into the development of new techniques for data analysis in order to cope with great streams of data collected by these instruments. Experimental Astronomy acts as a medium for the publication of papers of contemporary scientific interest on astrophysical instrumentation and methods necessary for the conduct of astronomy at all wavelength fields. Experimental Astronomy publishes full-length articles, research letters and reviews on developments in detection techniques, instruments, and data analysis and image processing techniques. Occasional special issues are published, giving an in-depth presentation of the instrumentation and/or analysis connected with specific projects, such as satellite experiments or ground-based telescopes, or of specialized techniques.
