The project aims to develop a new model for solar flares and pulsars that more realistically describes these phenomena. Solar flares and pulsars involve strong magnetic fields changing rapidly as a function of time, implying enormous inductive potentials. The project aims to show how the inductive field and the plasma response to it can be included in an electrodynamic theory. It plans to apply this theory to solar flares, and show how it can resolve the long-standing ‘number problem’. It also plans to apply the model to pulsars, and show how the long-standing dichotomy between the vacuum-dipole and rotating-magnetosphere models can be resolved by synthesising them. The project intends to combine these ideas into a new model for the most extreme examples of magnetic explosions: superflares and giant bursts on magnetars.

该项目旨在开发一个新的太阳耀斑和耀斑模型，更真实地描述这些现象。太阳耀斑和太阳耀斑涉及强磁场，其变化迅速，是时间的函数，这意味着巨大的感应电势。该项目旨在展示如何将感应场和等离子体对其的响应纳入电动力学理论中。它计划将这一理论应用于太阳耀斑，并展示它如何解决长期存在的“数字问题”。它还计划将该模型应用于恒星，并展示如何通过合成它们来解决真空偶极子和磁层模型之间长期存在的二分法。该项目打算将这些想法联合收割机组合成一个新的模型，用于磁爆炸的最极端例子：磁星上的超级耀斑和巨大爆发。
