«Whatever the cause, some heat does indeed leak back toward the solar surface, but the total
amount of energy so transported is
really quite
small, and can not raise the photospheric temperature very much.
Re: Myrrh says (March 2, 6:42 pm): «So, if as Ira says «the filament
of the incandescent light bulb is heated to temperatures similar to the Sun's surface», and we know such a lightbulb gives most
of its
energy in Heat and not Light, in Thermal IR, 95 %, and only a
small amount in Visible, only 5 %, then what is
really «the most»
energy given off by the Sun?»
