Revisiting the nature of dark sunspots: not magnetic, but thermal activity of the Sun

This article is a continuation of the works1-4 author, devoted to elucidating physical nature dark sunspots. It has been proven that scientific paradigm cold sunspots prevailing in solar physics erroneous, since it contradicts second law thermodynamics. photosphere can only be hotter than photosphere, and their visual darkness non-thermal nature. Sunspots are hottest areas Sun's surface, temperature which ~ 6∙106 K, they cause sources thermal energy activity phenomena. The empirical inconsistency concept magnetic Sun processes reconnection atmosphere proved. All unsolved problems physics, including heating corona, due false
