  We develop the general laws of the theory of the almost empty anchored
magnetic flux tubes (MFT) with B~10^7G, starting from tachocline to the surface
of the Sun. The main result of this theory is the formation of the solar axions
and the magnetic O-loop inside the MFT near the tachocline. In this magnetic
O-loop (based on the Kolmogorov turbulent cascade) the axions are converted to
photons, producing the axion origin photons near the tachocline. On the other
hand, high-energy photons from the radiation zone through the axion-photon
oscillations in the O-loop produce the axions of photon origin under the
sunspot. This means that at such strong magnetic fields the Parker-Biermann
cooling effect of MFT develops due to the "disappearance" of the Parker's
convective heat transport, and consequently, the temperature in the lower part
of the magnetic tube with the help of the axions of photonic origin near the
tachocline. As a result, a free path for photons of axion origin opens from the
tachocline to the photosphere!
  We show that the high-energy photons passing from the radiation zone turn
into axions, which almost completely eliminates the radiation heating of the
almost empty MFT. A certain flux of photons coming from the radiation zone
through the tachocline, passes through the "ring" of a strong magnetic tube by
virtue of convective heating. It allows to determine the velocity and the
lifetime of the MFT before the reconnection, from tachocline to the surface of
the Sun, as well as the rate of the MFT reconnection near the tachocline.
  Finally, we show that the formation of sunspot cycles is is the manifestation
of dark matter -- solar axions in the core of the Sun, whose modulations are
controlled by the 11-year modulation of asymmetric dark matter density in the
solar interior.
