ON THE THEORY OF FORMATION OF SHOCK WAVES IN THE CHROMOSPHERE AND IN THE CORONA,
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
Pagination or Media Count:
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.
