Compressible Magnetohydrodynamic Turbulence in Interstellar Plasmas
Compressible Magnetohydrodynamic Turbulence in Interstellar Plasmas
Radio wave scintillation observations reveal a nearly Kolmogorov spectrum of density fluctuations in the ionized interstellar medium. Although this density spectrum is suggestive of turbulence, no theory relevant to its interpretation exists. We calculate the density spectrum in turbulent magnetized plasmas by extending the theory of incompressible magnetohydrodynamic (MHD) turbulence …
