Solar radius is not affected by the solar variability

In the Scitechdaily article (see this an interesting question was posed.

How it is possible that the solar radius is not affected by solar cycle variability? This is one of the many questions which are popping as the existing view of solar physics is collapsing. The early cosmology and galactic physics collapsed first after the findings of James Webb telescope and now stellar physics is following!

TGD provides an immediate answer (for a background see the earlier blog posting)

1. The numerous anomalies of the Sun leave only one conclusion: the standard view of the solar interior is completely wrong. Only the surface layer, magnetic bubble, is active and generates solar wind.
2. The solar wind consists of matter emerging from the magnetic bubble forming a thin layer at the surface of the Sun. The nuclei of the solar wind from the Sun do not arrive from the solar core as fusion products but are created in a phase transition in which M_89 nucleons at long monopole flux tubes with mass 512 times the ordinary nucleon transform to ordinary nucleons and liberate almost all of their mass as kinetic energy and bosonic matter. These flux tubes form what I have called a magnetic bubble at the surface of the Sun. Solar core where fusion would be occurring is a mere fragment of imagination.
3. In fact, in a good approximation Sun is analogous to a quantum harmonic oscillator consisting of mass shells as magnetic bubbles and the evolution of the Sun gradually burns these layers. The analogy with atoms and nuclei is obvious: only the valence shells are active and inner shells are totally silent and interact with the external world! This kind of layered structure was one of the first suggestions of classical TGD about 40 years ago but I could not take it seriously.
4. Planets and supernovae correspond to massive explosions throwing out these shells and solar wind is caused by their local explosions.
5. Finally the answer to the question. The solar wind affects the corona. The interior of the Sun has no effects on the shape of the Sun since it is totally passive just like the inner shells of the atom. Astrophysics is extremely simple.
