论文摘要
Betelgeuse突然发生了亮度，并神秘地变暗。这可能是由于从槟榔从betelgeuse弹出的血浆热点引起的，然后冷却以遮盖灰尘。如果是真的，那将是一个非凡的机会，可以直接见证一颗红色超级巨星周围的灰尘形成。当今的光学望远镜设施未针对Betelgeuse表面进行时间进化监视，因此在这项工作中，我们提出了低成本的光学干涉仪。该设施将包括$ 12 \ times 4 $英寸的光学望远镜安装在大型无线电盘上进行干涉成像；维护极化的单模纤维将将相干光束从各个光学望远镜运送到多合一的梁组合器。快速转向镜辅助纤维喷射系统将通量引导成纤维。计量系统感受到光纤中振动诱导的活塞误差，这些误差通过快速延迟延迟线进行校正。我们将展示设计。
Betelgeuse has gone through a sudden shift in its brightness and dimmed mysteriously. This is likely caused by a hot blob of plasma ejected from Betelgeuse and then cooled to obscuring dust. If true, it is a remarkable opportunity to directly witness the formation of dust around a red supergiant star. Today's optical telescope facilities are not optimized for time-evolution monitoring of the Betelgeuse surface, so in this work, we propose a low-cost optical interferometer. The facility will consist of $12 \times 4$ inch optical telescopes mounted on the surface of a large radio dish for interferometric imaging; polarization-maintaining single-mode fibers will carry the coherent beams from the individual optical telescopes to an all-in-one beam combiner. A fast steering mirror assisted fiber injection system guides the flux into fibers. A metrology system senses vibration-induced piston errors in optical fibers, and these errors are corrected using fast-steering delay lines. We will present the design.
