Magnetic ionization fronts - III. Internal structures

We present calculations of the internal structures of stationary ionization fronts with oblique upstream magnetic fields. Solutions are found only wit hin the range of upstream parameters allowed by the evolutionary conditions derived by us in a previous paper. As is the case for hydrodynamic ionizat ion fronts, overheating of the gas within the front can mean that not all t he solutions allowed by the evolutionary conditions correspond to resolved internal structures. Some, but not all, of these jumps can be realized by s tructures with included subshocks: we present a full range of internal stru ctures for fronts close to criticality, and discuss how to avoid spurious ' strong-R' type solutions. The solutions we study suggest that significant transverse velocities and m odulations of the perpendicular magnetic field may characterize obliquely m agnetized ionization fronts. We briefly discuss the observability of the in ternal structures.
