- This paper describes the first simulation of Alfvén ionization in substellar atmospheres, presenting the innovative coupling of a gas-MHD interactions code with a state-of-the-art substellar global circulation model. This work is significant as it shows the resulting degree of ionization can outstrip that from traditional sources such as thermal ionization. This work has generated a new collaboration with the University of Bern & Oxford to investigate the role of dynamical feedback into the coupling mechanism – we are currently developing more advanced simulations. This work was presented as a contributed talk at the Institute of Physics Plasma Physics Conference 2019.
