Abstract

This project is devoted to the study of turbulence in astrophysical plasmas. Turbulence is one of the still not understood problems of classical physics. Similar to what happens for regular fluids on Earth, like air or water, astrophysical plasmas in space are found to behave in a turbulent way, developing vorticose motions over a broad range of scales. Due to its mathematical complexity turbulence has been studied in the last decades by means of numerical simulations. The difficult part of it relies on the need of resolving numerically a broad range of scales that all together constitute the phenomenology of turbulence. In this project we propose to conduct cutting edge numerical simulations of plasma turbulence using a numerical method that overcome several limitations in the description of plasma motions from large to small scales. This method will allow us to address still open questions on this topic with an unprecedented realism of the model and precision of the description. The results of this project will be useful for a better theoretical understanding of astrophysical plasma turbulence and will serve as a guidance for the interpretation of new spacecraft observations of heliospheric plasmas that are already or will be available in the near future.
