Magneto-gravity waves and the heating of the solar corona

摘要: It is generally believed that the heating of solar corona caused by waves originating in photosphere and propagating into where their energy dissipated. The medium through which these propagate general permeated magnetic fields complicating behaviour this propagation considerably. We have therefore analysed wave motions a plasma constant gravitational fields. In general, three modes were found, we called + mode, −mode, Alfven mode. Each mode was found to be strongly coupled each kinds motion; acoustic, gravity, hydromagnetic. However, separable from dispersion relation, independent compressibility gravity. local relation derived expressed nondimensional form constants describe particular atmosphere. From one can show rising either with or growing amplitude depending on magnitudes directions field, vector. variation density height taken account generalized W.K.B. method. Equations are give at reflection occurs, giving upper bound for possible propagation.
