This [emphasize] physical process was first used as the explanation for a related phenomenon by the CSHKP model. This process can leave behind voids called supra-arcade downflows in one environment. The Kadomtsev model implicates this phenomenon in “sawtooth crashes” where the safety factor plummets. “Ideal” tearing instabilities can lead to the collapse of (*) current sheets, which in turn drives this process. Spitzer resistivity is incorporated into an alternative to the Petschek model of this process, the (10[1])Sweet–Parker model. (10[3])This (10[1])process, which violates Alfven’s theorem, can occur “fast” (10[1])at high Lundquist numbers, violating ideal magnetohydrodynamics. For 10 points, name this phenomenon in which the magnetic topology of a (-5[1])plasma changes, the primary cause of solar flares. (10[2]0[2])■END■
