A METHOD OF ACOUSTIC POTENTIAL FOR ANALYS IS OF OSCILLATING SOLAR MODELS WITH REVISED CONVECTION THEORY

Dependence of solar acoustic oscillations on the structure of the supe radiabatic convection region is investigated with the method of acoust ic potential. To determine the role of the outer layers all the models were reduced to the same entropy in the adiabatic convection zone. In comparison with the standard mixing-length convection theory, the alt ernative theories of convection imply the both increase of the tempera ture gradient in the outermost layers of the convection zone and decre ase of the sound speed in the adiabatic convection zone. This leads to the better agreement between theoretical and observed frequency spect ra. The models demonstrate a satisfactory agreement (within 2 - 5 mHz) between the, theoretical and observed spectra of intermediate-degree eigenmodes.
