Abstract

NEID (NN-explore Exoplanet Investigations with Doppler spectroscopy) is an optical, fiber-fed spectrometer installed on the WIYN 3.5m Telescope. The radial velocity precision that NEID is expected to reach requires the stellar jitter (i.e., the slight irregular movement of the stellar image induced by atmospheric turbulence, wind-shake, etc.) to be controlled within 0.05 arc-seconds 90% of the time in nominal observing conditions (i.e., 0.8-arcsecond seeing and mild winds). To achieve that, the NEID Port Adapter incorporates a fast, first-order wavefront correction system, which implements an Electron-Multiplying CCD camera and a tip/tilt piezo stage to capture and stabilize the stellar image. Here, we use on-sky data to demonstrate the performance of this system under various observing conditions.
