论文摘要
我们介绍了Subaru/scexao+吸血鬼的H $α$高对比度成像的当前状态。我们在光学波长的自适应光学校正以及（双）光谱差异成像（SDI）和角度差异成像（ADI）的结合，能够检测OMI CET周围的环状特征，而H $α$α$对应物围绕Ry Tau。我们通过更改ADI和SDI的顺序以及达到的两个对比度限制来测试了后处理。 Magao。 Subaru/Vampires为北半球目标的H $α$高对比度成像提供了绝佳的机会。
We present current status of H$α$ high-contrast imaging observations with Subaru/SCExAO+VAMPIRES. Our adaptive optics correction at optical wavelengths in combination with (double) spectral differential imaging (SDI) and angular differential imaging (ADI) was capable of detecting a ring-like feature around omi Cet and the H$α$ counterpart of jet around RY Tau. We tested the post-processing by changing the order of ADI and SDI and both of the contrast limits achieved $\sim10^{-3}-5\times10^{-4}$ at $0.3^{\prime\prime}$, which is comparable to other H$α$ high-contrast imaging instruments in the southern hemisphere such as VLT/SPHERE, VLT/MUSE, and MagAO. Subaru/VAMPIRES provides great opportunities for H$α$ high-contrast imaging for northern hemisphere targets.
