Scientific paper

The observed speeds of coronal mass ejections are often below the estimated Alfvén speed but above the sound speed for the background solar corona. This suggests that slow magnetohydrodynamic shocks may form as mass ejections sweep through the corona. The authors argue on the basis of the Rankine-Hugoniot relations and the propagation of small-amplitude slow mode waves that the shape of a slow shock front would be flattened (with respect to a sun-centered sphere) or perhaps even concave outward (from the sun) and thus present a very different appearance from the fast coronal shock waves that have been commonly modeled as wrapping around a mass ejection.
