Hertzsprung-Russell diagrams and stellar evolution

Luminosity, LLL, is the total [     ] by a star; its SI unit is the [     ].

A

Luminosity, LLL, is the total energy emitted over its lifetime by a star; its SI unit is the joule, J.

B

Luminosity, LLL, is the total force exerted per unit area by a star; its SI unit is the pascal, Pa.

C

Luminosity, LLL, is the total energy emitted per unit time by a star; its SI unit is the watt, W.

D

Luminosity, LLL, is the total energy emitted per unit area by a star; its SI unit is the watt per square metre, W m−2^{-2}−2.
