✦ Synopsis

Progressive Alfv6n waves set the atoms in oscillatory motion. The radiation will be absorbed (emitted) at a Doppler-shifted wavelength; the Doppler shift is determined by the velocity given to the atoms by the wave. The effect of the waves on the line profile, integrated over one period, is given for a few simple cases. A brief discussion of the possible application to sunspots is presented.

The Rankine-Hugoniot equations for hydromagnetic shocks are extended to include the energy and momentum flux due to Alfvtn waves incident on the shock. The shock relations are solved numerically for a wide variety of parameters typical of interplanetary conditions. The presence of the waves can caus
