E)star's apparent brightness.

Question

Quizplus · Accepted Answer

The luminosity of light emerging from a star's gaseous surface is a direct result of the rate of energy generated from nuclear reactions in the star's core. This energy is produced through the process of fusion, in which light nuclei are combined to form heavier nuclei, resulting in the release of a large amount of energy. This energy is then transported to the surface of the star through convection and radiation, and is emitted as visible light. The mass of the star, its lifetime, the temperature of the core, and its apparent brightness are all factors that can affect the luminosity of a star, but the primary driver of this process is the rate of energy generated through nuclear reactions in the core.
