    Numerical Space Plasma Physics

     

    Frank Toffoletto’s research has focused on the development and use of computational models of the global-scale plasma physics of Earth’s magnetosphere. Computational modeling has become a major research tool in many branches of physics, most notably when it is used to enhance understanding of complex nonlinear systems. This is especially true for space plasma physics, where numerical modeling has become the research tool of choice for understanding a diverse set of physical problems related to space plasmas that are carefully vetted against in situ measurements. The tools and the insight that comes from developing and applying these computational models for Earth will likely play an important role in furthering our understanding of plasma environments throughout universe.


    At Rice, a major research focus has long been the development and use of computational models of Earth’s magnetosphere, with the primary tool for this work being the Rice Convection Model (RCM), developed over many years by Professor Richard Wolf and collaborators. The RCM describes the physical interaction of particles and fields in the inner and middle magnetosphere, that portion of Earth's environment controlled by Earth’s magnetic field extending to about 60,000 kilometers above the surface. In order to represent the physics of this region in a fully self-consistent fashion, the effects of the magnetospheric plasma on the magnetic field must also be included. To this end, we have developed a plasma equilibrium model (the RCM-Equilibrium, or RCM-E) that computes a self-consistent magnetic field in response to the plasma pressure specified by the RCM.  The RCM-E is a powerful tool that for the first time allows us to solve a complete set of self-consistent equations that describe the large-scale structure of the inner magnetosphere.  With this computational tool in hand we are now ideally positioned to address fundamental questions about the plasma physics of the near-Earth environment, especially in relation to storms and substorms, which are large-scale disruptions of Earth’s coupled magnetosphere/ionosphere system that result in a significant amount of energy transfer and dissipation and that have important space weather implications. 


    The multi-faceted approach of using computational techniques to understand the physics of the space environment has and will continue to yield exciting new insights. Our group at Rice is well situated to exploit new opportunities, our initial coupled models are proving to be important tools for understanding and representing physical processes in Earth’s magnetosphere; in the long term, as the models become increasingly sophisticated, we expect to obtain more and more insight into the chain of physical processes driving the complex Sun-Earth space environment.
