The Solar energy is generated in the core of the Sun where it is the 
hottest and densest, 
the inner 20 % of its radius.  In order to maintain thermal
equilibrium we must then understand how the energy is redistributed 
in the Sun, and moves from the center of
the Sun to the surface of the Sun.
All methods of energy transport such that 
heat moves from 
hot regions to
cool regions. 
There are three main ways 
stars transport energy:

The important transport mechanisms for the Sun are radiation transport and
convection.  |
