Question

Quizplus · Accepted Answer

A brown dwarf is a failed star that is not massive enough to sustain nuclear fusion in its core like a true star, but still emits heat and light due to its gravitational collapse. Black holes do not emit light, but rather are known for their strong gravitational pull. Protostars are early stage stars that are still undergoing gravitational collapse and are not yet emitting light. T Tauri stars are young stars in the pre-main sequence phase that emit light due to their internal heat from gravitational collapse and nuclear fusion.
