Luminosity

(L)
(measure of brightness)

Luminosity is the total rate of energy Emission by a star or other astronomical object, e.g., in Joules per second or watts, i.e., is the power of the starshine.

The term is also used in contexts other than as a "whole star" concept, e.g., speaking of the energy propagation of a star's core as the core's luminosity.
