论文摘要

首先,用于单个望远镜的光纤成像仪是使用单模纤维进行瞳孔重新映射的光谱模子,允许测量望远镜衍射极限。它集成在斯巴鲁望远镜的Subaru Coronagraphic Extreme自适应光学仪器上,它受益于非常稳定的可见光波前,从而使长时间的暴露量与以前的可能性相比,可显着地接触并具有明显的淡淡来源。天上的结果证明了该仪器检测恒星伴侣在Capella二进制系统的情况下分离43MA的能力。在极大的望远镜上,类似的方法将在非常高的角度分辨率下为伴侣检测和表征提供独特的科学机会。

FIRST, the Fibered Imager foR a Single Telescope, is a spectro-imager using single-mode fibers for pupil remapping, allowing measurements beyond the telescope diffraction limit. Integrated on the Subaru Coronagraphic Extreme Adaptive Optics instrument at the Subaru Telescope, it benefits from a very stable visible light wavefront allowing to acquire long exposure and operate on significantly fainter sources than previously possible. On-sky results demonstrated the ability of the instrument to detect stellar companions separated 43mas in the case of the Capella binary system. A similar approach on an extremely large telescope would offer unique scientific opportunities for companion detection and characterization at very high angular resolution.
