Recently, Hallinan et al. (2015) reported simultaneous radio and optical spectroscopic observations (obtained with the Karl G. Jansky Very Large Array (VLA) radio telescope and the Double Spectrograph (DBSP) on the 5.1 - m Hale telescope, respectively) of auroral emissions of an object at the end of the stellar main sequence (i.e. at the boundary between stars and brown dwarfs).

The experimental behavior supports the storm scenario the traveling atmosphere disturbances (TADs) of auroral origin and changes in the thermospheric wind are the main physical mechanisms driving equatorward - directed and vertical winds which in turn move the plasma along the magnetic field lines and raise the ionospheric peak height.
