How NEID Detected HD 86728 b

This infographic illustrates how the NEID spectrograph, mounted on the WIYN 3.5-meter Telescope at the U.S. National Science Foundation Kitt Peak National Observatory, a Program of NSF NOIRLab, uses radial velocity measurements to detect exoplanets. The spectrum shown is a small fraction of the full spectrum of HD 86728 b — the first exoplanet discovered independently by NEID — with the red and blueshift greatly exaggerated for visual purposes.
