The student will investigate the generation of waves and oscillations by reconnection, focussing on the merger and interaction of twisted magnetic flux ropes. Initially, simulations of reconnecting flux ropes will be performed using 2D magnetohydrodynamics. The resulting waves will be analysed and identified, and the dependence of their properties on the parameters of the flux ropes will be explored. The project will then develop to more advanced models, potentially extending to 3D and considering the acceleration on non-thermal particles using a test-particle approach. The implications of the model results for understanding Quasi Periodic Pulsations in solar flares will be considered.

学生将研究通过重新连接产生的波和振荡，重点是扭曲磁通绳的合并和相互作用。最初，将使用二维磁流体动力学对重新连接磁绳进行模拟。将分析和识别产生的波，并探讨其特性对磁绳参数的依赖性。然后，该项目将开发更先进的模型，可能扩展到 3D 并考虑使用测试粒子方法对非热粒子进行加速。将考虑模型结果对于理解太阳耀斑中的准周期脉动的影响。
