Solar Atmospheric Dynamics.
Abstract
This study seeks to calculate the generation and propagation of Magneto-Acoustic Gravity (M.A.G.) waves in the solar atmosphere and their effect on the heating of the chromosphere and corona. A computer program has been written, which is capable of integrating the equations of motion of such waves, which are inherently three-dimensional. To simplify the equations, without seriously distorting the nature of the motions, we impose a fixed horizontal modal structure consisting of 6 waves propagating horizontally in a hexagonal pattern. These equations need to be integrated in time and only one spatial direction - the vertical. The program is currently being tested for the simpler case of non-vertically propagating acoustic-gravity waves. We have also analyzed Skylab UV data for evidence of acoustic pulses in the transition region and calculated the steady state structure of the solar wind flow along a magnetic flux tube that diverges more rapidly than vertically.
