[44.08] A Technique for Incorporating Large-scale Magnetic Fields Within Stellar Models: Implications for the Variability of the Solar Radius, Luminosity, and Pulsation Frequencies

T.J. Lydon (Yale/CSSR), S. Sofia (Yale/CSSR)

A set of physically consistent approximations are employed to include the effects of magnetic fields within the equations of stellar structure. A series of solar models are then constructed with large-scale ($\approx0.1R_\odot$), intense ($\approx10^6$ gauss) magnetic fields. The results of such models are then compared to measurements of changes in the solar radius (from the Solar Disk Sextant Experiment) and changes in the solar p-mode frequencies in order to determine if such fields are associated with the solar cycle.
