Research Abstract

I focused my research on developing phenomenological exclusive prediction for other astrophysical objects than the sun as well as theoretically extending my original magnetic reconnection model (the self-similar model). My initial plan to focus on phenomenologically examining the self-similar model by using Hinode data of solar phenomena was changed due to the unexpected historical inactive phase of the solar magnetic activity. While the achievement of the initial plan is less than I expected, this program succeeded to progress phenomenological prediction about flux-emerging-type solar flares and chromospheric evaporations and also to progresstheoretical extension to the special relativistic model and to reconnection events in galactic wind termination shocks.
