Description
High resolution spectroscopy has proven a powerful and highly versatile tool in the characterization of exoplanet atmospheres. Over the last decade we have explored the rich detail that its sensitivity to the position and shape of exoplanet spectral lines provides, and with robustness thanks to the unique pattern of lines that each species exhibits at such high resolution. In this talk, I will review this playground for discovery in exoplanet atmospheres with an observer’s eye, focusing on the observational techniques it uses and their outputs. I will briefly explore its discoveries from abundances to the 3D dynamical nature of exoplanet atmospheres, from the ultra hot to the increasingly cooler and smaller planets. Despite a vast range of new discoveries, thanks to the deluge of new high resolution instruments from the EPRV community, we have barely only scratch the surface of what we can learn with high resolution spectroscopy. I will highlight current and future avenues for discovery, including with the ELTs. I will finish however with a primer for discussion during this workshop, on some of the challenges and the consensus that the field of high resolution spectroscopy of exoplanet atmospheres needs to face as we go towards the robust characterisation of potentially habitable worlds.
