What stellar remnant forms if an object cannot sustain hydrogen fusion, having a mass roughly below 80 times that of Jupiter?
Answer
Brown dwarfs
Stars less massive than about 0.08 times the mass of the Sun, or roughly 80 times the mass of Jupiter, cannot sustain hydrogen fusion in their cores and instead become brown dwarfs, often considered 'failed stars'.
