In this paper, we suggest that a solar flare may be triggered by a lack of thermal equilibrium rather than by a magnetic instability. The possibility of such a thermal nonequilibrium (or catastrophe) is demonstrated by solving approximately the energy equation for a loop under a balance between ther

A longitudinal stability is considered for the quasi-steady current sheet which is uniform along the current. In the MHD approximation, the stability problem is solved for the plane neutral sheet and small disturbances propagating along the current. The current sheet is shown to break-up into the sy
Recent observations of 'neutral line absorbing features' in the solar atmosphere may give an important clue to the mechanism whereby both type III solar radiobursts and solar flares are triggered. It is suggested that as new satellite magnetic flux emerges at the edge of an active region in an area
We review the observations and theory relating to the role of energetic electrons in the solar flare, with particular emphasis on discriminating between "thermal" and "nonthermal" origins of these electrons. We discuss diagnostics in hard X-rays, especially those relating to the recent observations
