| Abstract: | It is shown that a hypothetical relict magnetic field in the solar radiative-transport zone that penetrates into the convective
zone would affect the solar dynamo, resulting in radical changes in the butterfly diagrams. This would transform the traveling
waves of activity into standing waves. A comparison of our results with the well-known butterfly diagrams for the Sun gives
an upper limit of the order of some tens G for the value of relict magnetic field penetrating into the solar convective zone.
At the same time, it is not ruled out that such relict magnetic fields in other solar-type stars are strong enough to make
the activity waves become standing waves. |
