ESPRESSO - Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations
Summary
ESPRESSO is the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations installed at the incoherent combined Coudé facility of the VLT. It is an ultra-stable fibre-fed échelle high-resolution spectrograph (R~140,000, 190,000, or 70,000) which collects the light from either a single UT or the four UTs simultaneously via the so-called UT Coudé trains. The whole system is built to reach the ultimate radial-velocity precision of 10 cm/s over a timespan of 10 years in single UT mode. Read more...
