He also has developed many optical and infrared instruments such as the ground - based auroral imager and spectrometer and infrared Echelle spectrometer.

The required data can only be obtained with the largest telescopes on Earth such as the Keck Observatory on the summit of Mauna Kea, Hawaii equipped with the powerful High Resolution Echelle Spectrometer (HIRES) spectrograph to disperse the stellar light into its constituent colors and absorption features.

The astronomers used a highly specialized instrument called the High Resolution Echelle Spectrometer, or HIRES, mounted on the 10 - meter Keck - I telescope.

Planets «b, c, and d» - On December 14, 2009, a team of astronomers (Steven S. Vogt; Robert A. Wittenmyer, R. Paul Butler, Simon O'Toole, Gregory W. Henry, Eugenio J. Rivera, Stefano Meschiari, Gregory Laughlin, C. G. Tinney, Hugh R. A. Jones, Jeremy Bailey, Brad D. Carter, and Konstantin Batygin) announced the discovery of one innermost orbiting super-Earth and two outer - orbiting, Neptune - class planets (with at least 5.1, 18.2, and 24.0 Earth - masses, respectively) in moderately circular, inner orbits around 61 Virginis with periods of 4.2, 38.0, and 124.0 days, based on radial - velocity observations over 4.6 years with the Keck Observatory's High Resolution Echelle Spectrometer (HIRES) and the Anglo - Australian Telescope (U.C. Santa Cruz news release; AAO press release; Keck press release; the Lick - Carnegie Exoplanet Survey Team's «Systemic Console;» and Vogt et al, 2009).

On November 1, 2010, a team of astronomers working with the NASA - UC Eta - Earth Survey revealed the detection of a super-Earth in a torch orbit with a minimum of 8.2 + - 1.2 Earth - masses around BD +26 2184, using radial - velocity measures from the Keck Observatory's High Resolution Echelle Spectrometer (HIRES).

In order to confirm these findings, the team combined its observations with a series of previous ones made with HARPS, as well as with the more advanced High Resolution Echelle Spectrometer, or HIRES, at the Keck Observatory in Hawaii, and the Planet Finding Spectrograph, or PFS, at the Las Campanas Observatory in Chile.

New instruments introduced at Keck this year have expanded our research capabilities further, with the commissioning of the Keck Cosmic Web Imager (KCWI) and the Near Infra ‐ Red Echelle Spectrometer (NIRES).
