论文摘要
NIRPS（近红外行星搜索者）是AO辅助和纤维馈电光仪，可用于YJH波段中的高精度径向速度测量。 Nirps还具有特异性是SCAO辅助仪器，可以首次使用几种模式纤维。这种选择通过允许设计紧凑的低温光谱仪，同时在不良的看见条件和微弱的恒星下保持高耦合效率，从而提供了出色的权衡。主要缺点位于更重要的模态噪声中，这个问题必须解决1m/s精确的径向速度测量值。在本文中，我们介绍了NIRP的前端：其设计概述（光学力学，控制），其表现在天空中以及一路上学到的一些教训。
NIRPS (Near Infra-Red Planet Searcher) is an AO-assisted and fiber-fed spectrograph for high precision radial velocity measurements in the YJH-bands. NIRPS also has the specificity to be an SCAO assisted instrument, enabling the use of few-mode fibers for the first time. This choice offers an excellent trade-off by allowing to design a compact cryogenic spectrograph, while maintaining a high coupling efficiency under bad seeing conditions and for faint stars. The main drawback resides in a much more important modal-noise, a problem that has to be tackled for allowing 1m/s precision radial velocity measurements. In this paper, we present the NIRPS Front-End: an overview of its design (opto-mechanics, control), its performance on-sky, as well as a few lessons learned along the way.
