Recent Developments on Brown dwarfs

Newborn Brown Dwarfs Stir Up The Neighborhood: Astronomers have found a clutch of jets from newborn brown dwarfs, bringing the total of these intriguing objects found to 4. New stars form in cold clouds of gas and dust. These so-called stellar nurseries are not only home to forming stars (protostars) but also harbour forming brown dwarfs.[1]
Stellar Stillbirths: Brown Dwarfs Revealed As Third Class Of Celestial Bodies After Stars And Planets: Brown dwarfs need to be treated as a separate class of celestial body in addition to stars and planets, researchers have found. Until now, brown dwarfs had been merely regarded as stars which were below normal size. However, they may well be stellar 'miscarriages.'[2]

Brown Dwarfs Really Do Form Like Stars: Astronomers have uncovered strong evidence that brown dwarfs form like stars. Using the Smithsonian's Submillimeter Array, they detected molecules of carbon monoxide shooting outward from the object known as ISO-Oph 102. Such molecular outflows typically are seen coming from young stars or protostars. However, this object has an estimated mass of 60 Jupiters, meaning it is too small to be a star. Astronomers have classified it as a brown dwarf.[3]
