Particle simulations of collisionless tearing, reconnection and coalescence of magnetic fields for a sheet-pinch configuration show that reconnection is Sweet-Parker like in the tearing and island formation phase. It is much faster to explosive in the island coalescence stage. Island coalescence is the most energetic process arrl leads to large ion temperature increase and oscillations in the merged state. Similar phenomena have been observed in equivalent MHD simulations.Coalescence and its effects, as observed in our simulations, may explain many of the features of solar flares and coronal X-ray brightening.
