In the luminosity formula ($L oldsymbol{\propto} R^2 T^4$), what factor dominates to reduce the total light output of a White Dwarf given its high temperature?
Answer
The extremely small radius factor ($R^2$)
Because the radius ($R$) of a White Dwarf is extremely small, the resulting $R^2$ factor overwhelms the contribution of the high temperature factor ($T^4$) when calculating total luminosity.
