line that separates stars from brown dwarfs tagged posts

Artist’s conception of the Epsilon Indi system. The two brown dwarfs orbit their common center of mass, which in turn orbits the much more distant primary component, a Sun-like star. By mapping the orbital motion of the brown dwarfs, the team was able to determine their masses. Much like our Solar System’s giant planets, brown dwarfs are thought to have cloud belts that encircle the entire object and give it a striped appearance.
