Delta E. Yes.

Yes.

Yes.

Oops, here is your error.

The aether temperature is not merely a function of the local addition of
energy from starlight degradation. (Temperature is a function of E, not of
dE.) Starlight degradation is a miniscule contribution to the pre-existing
aether energy density. After all, the aether temperature (energy content)
is what drives gravitation. In fact, gravitation is a competing effect --
lowering the local aether temperature a tiny amount, in the vicinity of the
star.

Very close to uniform. Not uniform. Normal gravitation and light energy
are tiny variations on the pre-existing local energy density. (The sun's
surface gravitation is about 1 part in 10^8 of the maximum gravitational
acceleration.)
