UVMag：Space UV和可见分光偏振法
UVMag: Space UV and visible spectropolarimetry
摘要：
UVMag是一个空间飞行任务项目，配备了一台在紫外线和可见光范围内工作的高分辨率分光偏振仪。将在欧空局的M4电话会议上向欧空局提出这一M型飞行任务。UVMag的主要目标是测量所有类型恒星的磁场、风和环境，以更好地了解恒星的形成和演化以及恒星环境对周围行星的影响。紫外线和可见光分光偏振观测的突破性组合将使科学家能够同时研究恒星表面及其环境。这一任务的仪器挑战是设计一个高分辨率空间分光偏振计，在117 nm至870 nm的巨大光谱域中测量被观测恒星的全斯托克斯矢量。由于光学元件的色散和FUV中的双折射问题，该光谱范围是主要困难。由于该仪器将被发射到空间，偏振模块必须是鲁棒的，因此如果可能的话，仅使用静态元件。本文介绍了不同的设计可能性旋光仪在这一点上的项目。
英文摘要：
UVMag is a project of a space mission equipped with a high-resolution spectropolarimeter working in the UV and visible range. This M-size mission will be proposed to ESA at its M4 call. The main goal of UVMag is to measure the magnetic fields, winds and environment of all types of stars to reach a better understanding of stellar formation and evolution and of the impact of stellar environment on the surrounding planets. The groundbreaking combination of UV and visible spectropolarimetric observations will allow the scientists to study the stellar surface and its environment simultaneously. The instrumental challenge for this mission is to design a high-resolution space spectropolarimeter measuring the full-Stokes vector of the observed star in a huge spectral domain from 117 nm to 870 nm. This spectral range is the main difficulty because of the dispersion of the optical elements and of birefringence issues in the FUV. As the instrument will be launched into space, the polarimetric module has to be robust and therefore use if possible only static elements. This article presents the different design possibilities for the polarimeter at this point of the project.
