Аннотация:A solution is found for stationary radiative cooling of a planar, one-dimensional flow of ionized hydrogen through the front of a shock wave. The energy exchange between electrons and protons, electron heat conduction, and bremsstrahlung cooling are taken into account. The velocity of the unperturbed gas relative to the front is taken to be in the interval 3000 km/s < u_0 < 10 000 km/s. The calculated radiation spectrum is presented in the form of the dependence of the color temperature on the photon energy E in the interval 0.5 keV < E < 10 keV. The color temperature grows monotically with E, but remains substantially lower than the shock-front temperature.
