Cool. Very interesting!It's a peculiar case. The bow shock (in front of Mira) creates a heated plasma, which flows backwards and interacts with the cool ISM, resulting in a far UV emission from H2. That is unusual; most emissions we see come from atomic hydrogen, not molecular hydrogen.Hmm, so I suppose the effect of that friction - that is, the heating of the gas - is more long lived than any ionization effect on the gas?
