The Structure of the Solar Cycle and of the Activity Cycles of Late-Type Stars

It is shown that the description of the solar cycle that takes into account the odd zonal harmonic of the solar magnetic field allows us to deepen our knowledge of two important aspects of the solar activity. First, to clarify and expand predictions of the evolution of the cyclic activity of the Sun in the near future. Second, to develop a program for monitoring the spectrophotometric characteristics of radiation of the solar-type stars aimed at obtaining new information about their magnetic fields.
