Coronal Heating Problem

Authors: Nainan K. Varghese

Abstract: Sun's corona appears much hotter than its surface. Temperature of coronal region, which is farther from the surface by more than eight times the radius of sun, is estimated to be over 1 million degrees Kelvin while temperature of sun’s surface is only about 6000 degrees Kelvin. (Temperature at the center of sun is estimated at about 15 million degrees Kelvin). Earth, with average matter-density of 5515 Kg/m^3 and mean radius of 6360 km, has an atmosphere that extends to about 700 km (about 11% of radius). Beyond this distance there is no perceptible concentration of 3D matter-particles. On the other hand, sun with average matter-density of 1408 kg/m^3 and mean radius of 696000 km is determined to have an atmosphere that extends to its coronal region at a distance of about eight times its mean radius (about 800% of radius). It is absurd to think that sun can sustain concentration of matter-particles at this distance, with sufficient matter-density that can heat up to the estimated temperature of coronal region. As contemporary physical theories are unable to explain any logical mechanism that can produce this difference, it is considered as ‘coronal heating problem’ in physics. Alternative concept, presented in book ‘MATTER (Re-examined)’ has a logical mechanism that can produce observed radiation from coronal region (which is far beyond the limit of its atmosphere).
