ON THE THEORY OF FORMATION OF SHOCK WAVES IN THE CHROMOSPHERE AND IN THE CORONA,

Abstract

A hypothesis, the so-called 'acoustic theory', explaining the heating of the chromosphere and corona is examined. According to this hypothesis the mechanism of heating consists in the following: audio or magneto waves, originating in the sub-photospheric layers during convec tive movements, propagate upwards and at a certain altitude transform into shock waves, which lead to a sharp dissociation of same (dissipation of same). The thermal energy liberated there heats the gas of the chromosphere and corona to a high temperature, because the gas density is low. To analyze this theory it is necessary to take into consideration the conditions of transformation of audio waves into shock waves in a heterogeneous atmosphere, situated in a gravitational field, which is connected with definite mathematical difficulties. A method developed in recent years and applicable to the given problem is described.
