A comprehensive theory is developped to describe the expansion of a plasma into a vacuum with a two-temperature electron distribution function. The characteristics of the rarefaction shock which occurs in the plasma when the hot- to the cold-electron temperature ratio is larger than 9. 9 are investigated with a semi-infinite plasma. https://www.lightemupsequences.com/top-offer-SALE-Skylight-Quilt-PATTERN-P173-by-Fran-Gulick-Riley-Blake-INSTRUCTIONS-Only-Confident-Beginner-Precut-Friendly-Mult-super-offer/
