Keeping Exoplanet Science Caffeinated with ESPRESSO

Earth and Planetary Astrophysics 2022-08-10 v1 Instrumentation and Methods for Astrophysics

Abstract

The ESPRESSO spectrograph at ESO's Very Large Telescope (VLT) has, since it began science operations in October 2018, revolutionised exoplanet science. The combination of the large VLT mirrors and the high resolution and stability of the spectrograph is enabling the detection of small, low-mass planets as well as detailed studies of the planets' atmospheres. In this article, we present a brief overview of the first results from ESPRESSO and a hopeful glimpse towards the ultimate goal of reaching the radial velocity precision of 10 cm/s needed to detect an Earth-like planet.
