An Approximate Solar Model on Bethe's Law of Energy Generation.
Abstract
Bethe's law of energy generation on the carbon cycle, taken along with the stellar equations of equilib- rium, gives, for an assigned central temperature and composition, two central densities, p~ and Pc2, such that for a central density Pc < Pc1 there can be only a radiative transfer of energy and for Pc > Pc2 all stellar models will be entirely convective, with no radiative envelope. A stellar model of the convec- tive radiative type is possible only for a single p~ lying between Pc1 and p~. A stellar model with a central temperature of T~ = 20.2 X 106 K and an H2 content of 35 per cent, has been worked out and found to be in close agreement with the sun
