Brown Dwarfs: The Coolest Stars or the Hottest Planets?

Brown dwarfs (also called failed stars) are substellar objects that are not massive enough to sustain nuclear fusion of ordinary hydrogen ( H) into helium in their cores, unlike a main-sequence star. Instead, they have a mass between the most massive gas giant planets and the least massive stars, approximately 13 to 80 … Ver mais Early theorizing The objects now called "brown dwarfs" were theorized by Shiv S.
