/ Abstract
Departamento deFsica eAstronomia, Faculdade Cincias, Universidade do Porto,Rua das Estrelas, 4150-762PortugalReceived2013 Aug 29, accepted 2013 Nov1Published online 2014 Jan 15Keywords instrumentation: spectrographs –plantary systems –techniques: spectroscopicThe acronym ESPRESSO stems for Echelle SPectrograph for RockyExoplanets and Stable Spectroscopic Observations;this instrument will be the next VLThigh resolution spectrograph. The spectrograph will be installed at the Combined-CoudeL´ aboratory of the VLTand linked to the four 8.2mUnit Telescopes (UT) through four optical Coudet´ rains.ESPRESSO will combine efficiencyand extreme spectroscopic precision. ESPRESSO is foreseen to achieve again oftwomagnitudes with respect to its predecessor HARPS, and to improve the instrumental radial-velocity precision to reachthe 10 cms
