Brown dwarfs are considered the companion of another star in a binary star system. They are very dim and very cool therefore hard to discover. There are methods that help find brown dwarfs by X-Ray and gravity effect of the other companion star. Brown dwarfs were basically robbed of their gases from the dominate neigbor usually a white dwarf similar to our own sun. They range in size of about Jupiter or larger. They emit no radio transmission or light. Brown dwarf is really a temporary name as of now and will be re-classified if not already. It has been speculated that our system is host to a brown dwarf on the outlaying perimeter of out solar system that could be the influence of comets in their unusual path. Because of the fact they are hard to find it would probably take a satillite probe to find it. Brown dwarfs were first theorized in the 1950`s and not proven until just recently. Hope this helps a little. Check out this months issue of Astronomy; there is an artical on binary systems that mention brown dwarfs.
