Question

Quizplus · Accepted Answer

Stars with luminosities between 50 and 100 times that of the Sun but spread over a range of temperatures are typically in the post-main-sequence stage of evolution. This stage occurs after a star has exhausted the hydrogen in its core and has moved off the main sequence, leading to a spread in temperatures as the star evolves through different processes such as expanding into a giant.
