Brown Dwarfs Do Form Like Stars

This artist's conception shows the brown dwarf ISO-Oph 102. Observations by the Submillimeter Array suggest that it is forming like a star, by accumulating material from the surrounding accretion disk (orange) shown here. The brown dwarf sheds angular momentum by ejecting material in two
oppositely directed jets (red). Blue bow shocks indicate where those jets are interacting with the interstellar medium.


This artist's conception zooms in on the brown dwarf and its accretion disk. The discovery of a bipolar molecular outflow at ISO-Oph 102 offers the first strong evidence in favor of brown dwarf formation through gravitational collapse.
