Descripción
We have analyzed the differences in the oscillation eigenfrequencies
measured over more than two years of GONG observations (December
1995-April 1998) and SOI/MDI observations (May 1996-July 1998). We have
inverted these data to look for signatures of the solar activity cycle
on the stratification. A one-dimensional (radial) structure inversion
code was used to study temporal variations of the sound speed
distribution at the boundary between the radiative and convective zones.
Such variations could be an indication of the presence of a toroidal
magnetic field anchored in this region.
