HD 86728 b Archives

This artist’s illustration shows HD 86728 b, the very first exoplanet to be discovered by 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. Exoplanet HD 86728 b is about nine times more massive than Earth. Surprisingly, this super-Earth appears to be the only planet orbiting its star. Credit: NOIRLab/NSF/AURA/P. Marenfeld

NEID Earth Twin Survey Delivers On Its Goal to Push the Limits of Exoplanet Discovery

by Keith CowingNovember 23, 2024

For four years the NEID (rhymes with fluid) spectrograph, mounted on the WIYN 3.5-meter Telescope at U.S. National Science Foundation Kitt Peak National Observatory (KPNO), a Program of NSF NOIRLab, […]

Complete RV time series for HD 86728. The NEID data are shown as light (Run 1) and dark (Run 2) blue circles, the APF data are shown as red squares, HIRES as orange hexagons, and Lick as purple diamonds. We also show the best-fit model (black), and in the lower panel we show the residuals to this model. -- astro-ph.EP
