Compressible Magnetohydrodynamic Turbulence in Interstellar Plasmas

  title={Compressible Magnetohydrodynamic Turbulence in Interstellar Plasmas},
  author={Yoram Lithwick and Peter Goldreich}
Radio wave scintillation observations reveal a nearly Kolmogorov spectrum of density Ñuctuations 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 given by Goldreich & Sridhar to include the e†ects of compressibility and particle transport. Our most important… CONTINUE READING
