Fiber-fed high-resolution visible-light echelle spectrograph
with radial velocity capabilities
The five-year data collection, made possible with an instrument called Texas Echelon Cross Echelle Spectrograph
installed on the IRTF, allowed researchers to study a full cycle of QQO, the first study to have done so.
Keck Observatory in Hawaii, using the Near Infrared Echelle Spectrograph
Tau Bootis b does not transit in front of its parent star from our viewpoint on Earth, but Lockwood and colleagues were able to tease out the weak light emitted by the planet using the Near Infrared Echelle Spectrograph
(NIRSPEC) at the Keck Observatory in Hawaii.
 ESPRESSO, the Echelle SPectrograph
for Rocky Exoplanet and Stable Spectroscopic Observations, is to be installed on the ESO Very Large Telescope.
Christian Buil has used an echelle spectrograph
to measure the Doppler shift of stars with orbiting planets.
The SpectraPro HRE high resolution echelle spectrograph
is suited for use with the proprietary CCD and ICCD camera systems.
Installed on the ESP 3.6 m Telescope in Chile, HARPS - along with the Ultraviolet and Visual Echelle Spectrograph
instrument on ESO's Very Large Telescope, also in Chile - was used to confirm the existence of Proxima b.
Using data of tau Bootis b from the Near Infrared Echelle Spectrograph
(NIRSPEC) at the W.
Once a student feels proficient in the basics, he or she can use a simulated telescope and photon-counting spectrometer (patterned after an echelle spectrograph
on the Multiple Mirror Telescope) to take spectra of several stars, which can then be saved and compared.
As part of the study, the researchers used the large eight-meter Gemini North telescope in Hawaii and an instrument called the Texas Echelon Cross Echelle Spectrograph
