Three dimensional MHD simulations of the dynamics and energetics of coronal flux tubes
... Although the effective values of resistivity and viscosity within the corona are not well constrained, they are estimated to be many orders of magnitude below the lev- els of η and ν that we have found to suppress the ...

Nonlinear MHD waves and discontinuities in the Martian magnetosheath Observations and 2D bi ion MHD simulations
... This coupling in a multi-ion plasma leads to the appear- ance of additional compressive wave modes and prompts a question about multi-ion shocks. Indeed, Dubinin et al. (1996b, 1997) have observed multiple shocklets in ...

Solar prominences embedded in flux ropes : morphological features and dynamics from 3D MHD simulations
... The results of the previous section indicate that resonant absorption is responsible for the attenuation of the position of the CM. This is true at least for the case of the light prominence. The results for the typical ...
