Future Exoplanet Research: Radio Detection and Characterization

International audienceAuroral radio emission from extrasolar planets can constitute a treasure trove of information difficult or impossible to obtain otherwise. To date, no confirmed radio detection has been achieved, even though a certain number of observations have been conducted and a host of theoretical studies have been published. The current status of radio studies of extrasolar planets and their auroral emission has been described elsewhere in this book; here, we take a look into what the future might bring. For this, we discuss the developments that are currently ongoing and describe how they could shape the field of exoplanet research in the future. In particular, we investigate improvements to existing radio telescopes, plans for future ground-based radio telescopes, future space-based radio telescopes, and a potential future radio telescope on the Moon. We try to evaluate the potential for new discoveries for each of these cases
