CARMENES仪器由两个交叉色散的中阶梯光栅光谱仪组成，它们共同覆盖5，200至17，100毫安的波长范围。在其在西班牙卡拉尔阿尔托3.5米望远镜上运行的头五年中，它被用于对365 M矮星进行径向速度测量，对凌日系外行星进行后续径向速度观测，并对凌日期间系外行星大气进行光谱研究。CARMENES的数据还提供了大量关于M矮星基本参数和活动的信息。我们概述了2016年至2020年CARMENES主要调查的科学结果。
The CARMENES instrument consists of two cross-dispersed ´echelle spectrographs, which together cover the wavelength range from 5,200 to 17,100 ˚A. During its first five years of operation at the 3.5 m telescope on Calar Alto, Spain, it has been used for a radial-velocity survey of 365 M dwarfs, for follow-up radial-velocity observations of transiting exoplanets, and for spectroscopic studies of exoplanet atmospheres during transits. The CARMENES data have also yielded a wealth of information on the fundamental parameters and activity of M dwarfs. We provide an overview of the scientific results from the main CARMENES survey in the years 2016 to 2020.
