论文摘要
我们描述了Subaru Coronagraphic Extreme Adaptive Optics（SCEXAO）仪器在夏威夷Maunakea上的Subaru望远镜上的当前表现。 Scexao将继续提高其AO性能，对于明亮的恒星，H Band strehl比率超过0.9。我们用ScExao的波前控制来描述新的进步，从而在光学的，修改中导致更稳定的校正波前和衍射受限的成像，以更好地处理Charis内部的读取噪声抑制，并测试Charis内的分光光度计量学的精度和精度。我们概述了CHARIS数据处理管道中输出出版级数据产品的步骤。最后，我们注意到最近和即将到来的科学结果，包括发现新直接成像的系统和多波伦长度，对行星形成磁盘的更深刻表征以及即将到来的技术进步，这些技术将提高SCEXAO的Sciencec功能。
We describe the current on-sky performance of the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument on the Subaru telescope on Maunakea, Hawaii. SCExAO is continuing to advance its AO performance, delivering H band Strehl ratios in excess of 0.9 for bright stars. We describe new advances with SCExAO's wavefront control that lead to a more stable corrected wavefront and diffraction-limited imaging in the optical, modifications to code that better handle read noise suppression within CHARIS, and tests of the spectrophotometric precision and accuracy within CHARIS. We outline steps in the CHARIS Data Processing Pipeline that output publication-grade data products. Finally, we note recent and upcoming science results, including the discovery of new directly-imaged systems and multiwavelength, deeper characterization of planet-forming disks, and upcoming technical advances that will improve SCExAO's sciencec capabilities.
