The Solar Furnace

  • Claudio Vita-FinziEmail author


The accepted scheme for the solar interior is a core powered by nuclear fusion primarily via the p-p reaction. The validity of the Standard Solar Model for the Sun’s related metabolism can be assessed by reference to the associated flux of neutrinos. A temperature of 15 million K at the core falls to ~6000 K at the photosphere and rises to 20,000 K at the chromosphere and to 1–2 million K or more at the outer margins of the solar corona; most of the mechanisms currently favoured for this progression hinge on magnetic reconnection or on wave heating, whereas the scheme advanced here is a stepwise sequence, with induction heating at the photosphere, the Joule-Thomson effect in the chromosphere, and plasma expansion in the corona, a tripartite solution which also explains the threefold structure of the solar atmosphere.
