Abstract

MAROON-X is a fiber-fed, red-optical, high precision radial velocity spectrograph recently commissioned at the Gemini North telescope on Mauna Kea, Hawai’i. With a resolving power of 85,000 and a wavelength coverage of 500–920 nm, it delivers radial velocity measurements for late K and M dwarfs with sub-50 cm s⁻¹ precision. MAROON-X is currently the only optical EPRV spectrograph on a 8 m-class telescope in the northern hemisphere and the only EPRV instrument on a large telescope with full access by the entire US comm report here on the results of the commissioning campaign in December 2019 and early science results.
