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.bekindtopets.com/flash-pick-University-of-Nebraska-Winter-Break-Ear-Warmer-limited-super/
