Abstract
We consider structure and emission properties of a pair plasma fireball that cools due to radiation. At temperatures the cooling takes a form of clearly defined cooling wave, whereby the temperature and pair density experience a sharp drop within a narrow region. The surface temperature, corresponding to the location where the optical depth to infinity reaches unity, never falls much below keV. The propagation velocity of the cooling wave is much smaller than the speed of light and decreases with increasing bulk temperature.
