论文摘要
我们描述了Scexao/Vampires的可见光lyot coronagraph的设计和初始结果。 Coronagraph由四个顽固的，部分透射的焦平面面具组成，内部工作角度分别为36 MAS，55 MAS，92 MAS和129 MAS。 Lyot停止是一种反射性的，尺寸不足的设计，几何吞吐量为65.7％。我们的初步对比度为1E-2，在0.1“至1E-4的0.75”下为1e-4，对于所有面膜尺寸。 Coronagraph于2022年初部署，可开放使用。
We describe the design and initial results from a visible-light Lyot coronagraph for SCExAO/VAMPIRES. The coronagraph is comprised of four hard-edged, partially transmissive focal plane masks with inner working angles of 36 mas, 55 mas, 92 mas, and 129 mas, respectively. The Lyot stop is a reflective, undersized design with a geometric throughput of 65.7%. Our preliminary on-sky contrast is 1e-2 at 0.1" to 1e-4 at 0.75" for all mask sizes. The coronagraph was deployed in early 2022 and is available for open use.
