Molecular outflows and the origin of brown dwarfs

Tóm tắt

Brown dwarfs are on the dividing line between planets and stars. Up to date, about 1,000 brown dwarfs, including the coolest known brown dwarfs with temperatures of ~300 K as cool as the human body, have been discovered. However, the origin of these objects is still not well understood. This paper presents the result of molecular outflows from brown dwarfs in r Ophiuchi and Taurus. The observations of brown dwarfs at early stages provide key information to understand their formation mechanism.
