Steady and Fluctuating Parts of Sun’s Internal Magnetic Field
We have modeled the ‘steady’ part of sun’s internal poloidal magnetic field in the form of a central dipole and a central hexapole with strengths (0.6±0.1) and embedded in an asymptotically uniform field B o . A small deviation from isorotation seems to indicate:(i) a slow build-up of toroidal field...

. A small deviation from isorotation seems to indicate:(i) a slow build-up of toroidal field near the base of the convection zone and (ii) presence of torsional MHD perturbations in the outer radiative core, with latitudinal structure and time scales which may be similar to those of solar activity. |
