Abstract
The outer layers of the sun consist of two regions, both at a higher temperature than the surface of the sun. These are the chromosphere and the corona. The upper regions are at a temperature of the order of 106 °K, compared with 4800 °K for the solar surface. At first sight, this appears to be thermodynamically impossible, since heat travels from hot regions to cold regions.
