MAROON-X：北双子座EPRV的头两年
MAROON-X: The first two years of EPRVs from Gemini North
摘要：
MAROON-X是位于夏威夷莫纳克亚山的8米双子北望远镜上的光纤馈电光学EPRV光谱仪。MAROON-X于2019年12月作为访问仪器投入使用，并自2020年5月起定期使用。该仪器最初是为M-矮星的RV观测而设计的，用于广泛的系外行星和恒星科学案例，并在多个学期内转变为双子座北的第二大要求仪器。我们在这里报告的头两年的业务和径向速度观测。MAROON-X在天空中经常达到低于m/s的RV性能，短期仪器噪声基底为30 cm/s。我们将讨论实现这种精度水平的各种技术方面，以及如何进一步提高长期性能
英文摘要：
MAROON-X is a fiber-fed, optical EPRV spectrograph at the 8-m Gemini North Telescope on Mauna Kea, Hawai'i. MAROON-X was commissioned as a visiting instrument in December 2019 and is in regular use since May 2020. Originally designed for RV observations of M-dwarfs, the instrument is used for a broad range of exoplanet and stellar science cases and has transitioned to be the second-most requested instrument on Gemini North over a number of semesters. We report here on the first two years of operations and radial velocity observations. MAROON-X regularly achieves sub-m/s RV performance on sky with a short-term instrumental noise floor at the 30 cm/s level. We will discuss various technical aspects in achieving this level of precision and how to further improve long-term performance
