Abstract : Our previous conjecture that certain puzzling observations of electromagnetic effects in the Star Fish burst area could be understood as resulting from the effects of charge exchange is supported by further arguments and calculations. The conditions for copious charge exchange are discussed and shown to obtain for Star Fish. Estimates are given for the velocity distribution of the escaping fast neutrals, for the pre-ionization they produce, and for the location of their first re-ionization. DAC-code results for piston location, attenuation, and radio brightness temperature are presented. The energy spectrum and the number density of photoelectrons in the region of the debris expansion is calculated, based on an x-ray spectrum calculated by Longmire. Various problem areas in understanding Star Fish are discussed, including the field-line jet, the stability of the bubble, and the deposition of the energy carried by the charge-exchange neutrals.
