| Description: | Auroral processes and radio power at exoplanets In the solar system, planetary auroras and auroral emissions (such as coherent radio bursts) provide a means of diagnosing energetic processes in the space environment of planets, and such emissions could yield vital information about the characteristics of astrophysical objects that we cannot reach with spacecraft. In this presentation we discuss the development of a theoretical understanding of the behaviour of the magnetospheres and auroral processes at exoplanets in order to estimate the radio power from systems of various configurations. In particular, we discuss the star-planet interaction of close-orbiting planets that may be analogous to the interaction of Jupiter and its satellites, and the modelling of magnetosphere-ionosphere coupling at exoplanets as estimated using a 3D magnetohydrodynamic model. |
