Question

Quizplus · Accepted Answer

A main-sequence star's luminosity is directly proportional to the rate at which it converts hydrogen to helium through nuclear fusion. This is known as the star's "nuclear burning rate." Mass, distance, and radius can also be inferred from luminosity, but not directly. Instead, they must be calculated using other observable properties such as temperature, color, and spectral type.
