The ionospheric Alfvén resonator (IAR) is the cavity in the low magnetosphere between the conducting bottom of the ionosphere (normally, the ionospheric E region) and the strong gradient in the Alfvén speed at the altitude 0.1–1.0 RE. The idea about this resonator was first introduced by Polyakov and ...
Le rayonnement ultraviolet solaire qui est à l’origine de l’ionosphère réagit sur une partie des molécules atmosphériques en les amputant d’un électron. Un plasma, qui contient des nombres égaux d’électrons et d’ions positifs, est ainsi créé. L’électron, qui est léger, reçoit une vitesse considérable de façon que le gaz électronique obtient une température élevée (de l’ordre de mille kelvins) bien a…
