The Base of the Convection Zone and the Solar Magnetic Cycle : Seismic Detection of Their Connectionm

It is now possible to detect small variations with time of the characteristics of the transition at the bottom of the solar convection zone, as determined from the periodic signal in the frequencies. Such measurements may allow us to establish whether and in what manner the deeper convection zone changes with the solar magnetic cycle. This is important for understanding the dynamics at the base of the convection zone and the origin of the solar cycle. It will also help in understanding the physics of convective overshoot, its interaction with rotation and magnetic elds, and the eeects on the stratiication. In this work we investigate the detectability of small changes in the strat-iication at the base of the convection zone, and attempt to constrain the amplitude of the changes from currently available seismic data.
