Please join the Lowell Center for Space Science and Technology and the Space Science Lab for a virtual talk by Xueyi Wang on Thursday, April 28 at 11 a.m. EST.
Abstract:
Global hybrid simulation is a powerful tool to address the solar wind-magnetosphere interaction. Solar wind particles drive an array of physical processes in the global magnetosphere through wave-particle interaction. Electromagnetic compressional waves are generated in the Q-|| bow shock and foreshock regions, where reflected and backstreaming ion beams interact with the incoming solar wind. The bow shock ions possess a diffuse distribution with a non-thermal spectral break. Ion acceleration/heating is mainly through scattering between upstream and downstream waves. Reconnection flux ropes and bubbles in the tail are generated and propagate earthward with strong ion temperature anisotropy and non-Maxwellian distributions, providing localized and time-dependent injection sources to the inner magnetosphere. An empirical outflow model has been employed in the current kinetic simulation model to explore the global properties of O+in the magnetosphere.
Brief bio:
Wang. received his Ph.D degree in space physics in Chinese Academy of Science in 1998. He became an associate professor in Center for Space Science & Applied Research (CSSAR) in china in 1998. He joined Auburn university as a postdoc in 2000 and became a full research professor in 2020. His research activities is mainly in space plasma physics and basic plasma physics. He developed three kinetic simulation code: 3-D global hybrid model (Angie3D), the general curvilinear particle in cell code (GCPIC) and a gyrokinetic electron and fully kinetic ion model (GeFi).
