Gas dynamic processes in the chromosphere of a red dwarf, on which a beam of accelerated electrons with a power spectrum is incident for 10 sec, are considered. The ionization and radiation losses of hydrogen are determined separately for layers that are transparent and opaque in the line L-alpha. A discontinuity of the temperature propagates downward in the chromosphere, and a shock wave with high compression is formed in front of it. A dense region is formed at a height of about 1500 km with a density greater than 10 to the 15th/cu cm and a T of 9000 K; this region expands from a thickness of 1 km to 10 km. White radiation in the flares results when the dense region becomes strongly opaque in the Balmer lines. The Balmer losses cannot compensate for the heating, and a rise in the temperature in the dense region leads to the appearance of the optical continuum.
