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.

学生将研究通过重联产生波和振荡，重点是扭曲磁通量绳的合并和相互作用。最初，重新连接磁通绳的模拟将使用2D磁流体力学进行。将分析和识别由此产生的波，并探讨其性质对磁通绳参数的依赖性。然后，该项目将开发更先进的模型，可能扩展到3D，并使用测试粒子方法考虑非热粒子的加速。模型的影响，了解太阳耀斑的准周期脉动的结果将被考虑。
