CARMENES 仪器是一对高分辨率 (R⪆80,000) 光谱仪,覆盖 0.52 至 1.71 μm 的波长范围,针对精确径向速度测量进行了优化。它于 2015 年在西班牙南部卡拉阿尔托天文台的 3.5 m 望远镜上安装并投入使用。CARMENES 的第一个大型科学计划是对约 300 M 矮星的调查,于 2016 年 1 月 1 日开始。我们概述了 CARMENES 的所有子系统(前端、光纤系统、可见光摄谱仪、近红外摄谱仪、校准单元、标准具、设施)控制、联锁系统、仪器控制系统、数据缩减管道、数据流和归档),并概述项目的组装、集成、验证和调试阶段。我们展示了初步结果并讨论了卡门尼斯科学用途的进一步计划。
The CARMENES instrument is a pair of high-resolution (R⪆80,000) spectrographs covering the wavelength range from 0.52 to 1.71 μm, optimized for precise radial velocity measurements. It was installed and commissioned at the 3.5m telescope of the Calar Alto observatory in Southern Spain in 2015. The first large science program of CARMENES is a survey of ~ 300 M dwarfs, which started on Jan 1, 2016. We present an overview of all subsystems of CARMENES (front end, fiber system, visible-light spectrograph, near-infrared spectrograph, calibration units, etalons, facility control, interlock system, instrument control system, data reduction pipeline, data flow, and archive), and give an overview of the assembly, integration, verification, and commissioning phases of the project. We show initial results and discuss further plans for the scientific use of CARMENES.
