论文摘要
Keck Planet Imager和特征器（KPIC）是对Keck II自适应光学系统和仪器套件的升级，其目的是改善直接成像和高分辨率的光谱特性能力，以实现巨型系外行星。 KPIC I期包括一个新的金字塔波前传感器下游的纤维注入单元（FIU），将行星光耦合到馈入NIRSPEC的单个模式纤维，这是Keck的高分辨率红外光谱仪。这可以使直接成像系外行星的高分散光谱（HDS）在较小的分离和更高的对比度下，从而提高了这些物体的光谱表征能力。在这里，我们报告了KPIC I期FIU调试的绩效结果，包括分析仪器的吞吐量，稳定性和灵敏度。
The Keck Planet Imager and Characterizer (KPIC) is an upgrade to the Keck II adaptive optics system and instrument suite with the goal of improving direct imaging and high-resolution spectroscopic characterization capabilities for giant exoplanets. KPIC Phase I includes a fiber injection unit (FIU) downstream of a new pyramid wavefront sensor, coupling planet light to a single mode fiber fed into NIRSPEC, Keck's high-resolution infrared spectrograph. This enables high-dispersion spectroscopy (HDS) of directly imaged exoplanets at smaller separation and higher contrast, improving our spectral characterization capabilities for these objects. Here, we report performance results from the KPIC Phase I FIU commissioning, including analysis of throughput, stability, and sensitivity of the instrument.
