Titolo: “Retrieving the Atmospheres of Distant Worlds: Insights from High-Resolution Spectroscopy”
Abstract: “High-resolution (HR) transmission spectroscopy has demonstrated exceptional effectiveness in detecting multiple molecular species in the atmospheres of exoplanets. At HR, molecular absorption bands are resolved into thousands of individual spectral lines, allowing for unambiguous identification of species through line matching (e.g., via cross-correlation) with planetary model templates, even when most individual lines are buried within photon noise. The next frontier is to connect the detection of molecular species to the underlying chemical and physical properties of exoplanetary atmospheres. We discuss the prospects of this technique in the context of upcoming facilities, such as the Extremely Large Telescope (ELT), highlighting its potential to revolutionize our understanding of exoplanet atmospheres.”
