Abstract
Dynamical processes in current sheets in the coronae of the Sun and stars are supposed to be the origin of various impulsive energy release phenomena ranging from non-resolvable events (‘nanoflares’) up to the largest flares. The occurrence of hard X-ray and radio spikes with time scales Δt down to ~ 0.02 s in flares suggests that the energy release is fragmentary, occurring in small parts of the whole energy release region at scales l ~ V A Δt ~ 107 cm (for coronal parameters N = 1010 cm−3, T = 2.5 × 106 K, B = 200 G).
