This astronomical action may be followed by a coronal mass ejection.
One model for the structure of this astronomical action is based on the Hall effect and assumes that outflow is driven by dispersive waves to account for the Petschek shock structure. That model of this one-word action was an update to the SweetÂ–Parker model. This kind of action and an accompanying storm caused the breakdown of many instruments during the so-called Bastille Day Event. This kind of action gives its name to a class of stellar objects such as UV Ceti and Barnard's Star. This astronomical action is thought to be caused by the breaking up and refusing of field lines via magnetic reconnection. This astronomical action may be followed by a coronal mass ejection. For 10 points, identify this action that names a class of variable stars whose brightness increase suddenly, which also names a sudden increase in brightness of the Sun.
