The Nuclear Cow is Driving...

$T_{boom\,p}$ is when the matter is most nuclear, given density.

$T_{boom\,p}=v^2_{boom}.\cfrac{M_m}{2R}$

$v_{boom}=3.4354*\cfrac{density}{Z}$

Change in phase (melting and boiling) need not be at when the matter is most nuclear.  But radiation from the matter is highest at this temperature, $T_{boom\,p}$ when it is most nuclear.  Such radiation is not derived from the heat source that warms the matter, but from $v_{boom}$ within the matter.

And the nuclear cow drives the cart, looking for evidence..., the cart is still before the cow, nuclear or not.
