Abstract
Technically, the magnetic reconnection is ignited due to the shock wave which inevitably develops when the dark matter nuggets enter the solar atmosphere with velocity vAQNâ¼600kmâs which is much higher than the speed of sound cs, such that the Mach number M=vAQNâcsâ«1. These shock waves generate very strong and very short impulses expressed in terms of pressure Îpâpâ¼M2 and temperature ÎTâTâ¼M2 in vicinity of (would be) magnetic reconnection area. We find that this mechanism is consistent with X-ray observations as well as with observed jet like morphology of the initial stage of the flares. The mechanism is also consistent with the observed scaling of the flare distribution dNâ¼WâαdW as a function of the flare's energy W. We also speculate that the same nuggets may trigger the sunquakes which are known to be correlated with large flares.
