Abstract
In recent years the exoplanet community has been striving more and more towards the characterisation of extra-solar planets. This goal encompasses several different aspects and questions that surround the field, such as planet formation, evolution and composition. One very important component of a planet is its atmosphere, which can be observed via the transmission spectroscopy method, giving us invaluable insights regarding its composition, dynamics and properties. The easiest targets for this approach are ultra-hot Jupiters, a class of exoplanets characterised by their large sizes and high temperatures. This class of planets has emerged as the optimal testbed for atmospheric studies, as they provide the best conditions to observe their atmospheres. One of these planets is the recently discovered WASP-178 b, whose atmosphere we observed for the first time in the visible range of light and in high resolution with the ESPRESSO instrument. These observations allowed for intriguing findings on the atmosphere of a new ultra-hot Jupiter on our radar.
