Effects of partial ionization and pressure on hydromagnetic ionizing waves

The transverse hydromagnetic ionizing wave is studied theoretically without the assumption of infinite conductivity behind the wave. Finite gas pressures are included, as well as a variable degree of ionization behind the wave. The electric field in front of the wave is employed as a parameter. Jump conditions across the wave are solved. It is shown that finite pressure and variation of the degree of ionization are important in some regions. (Author).
