PROPAGATION OF NONLINEAR LONGITUDINAL-TRANSVERSE WAVES ALONG MAGNETIC-FLUX TUBES IN THE SOLAR ATMOSPHERE .2. THE TREATMENT OF SHOCKS

Equations were derived permitting the treatment of shocks which occur in longitudinal-transverse waves propagating in thin magnetic flux tub es. Such waves usually lead to kinks which may grow into oblique shock s. The kink angles between the shock and the tube directions are found to be symmetrical with respect to the shock. Purely longitudinal shoc ks occur only in special cases of high symmetry or of well defined pro pagation conditions. Wave calculations were performed which show the f ormation of oblique shocks. We also discuss recent suggestions that th e basic equations for the treatment of longitudinal-transverse waves a re incomplete.
