"Most brown dwarfs are 'failed stars', objects that were born with too little mass to shine brightly by fusing hydrogen in their cores."

Magma - lava on Earth clearly shows that there is no fusion, and the weight has nothing to do with "to shine brightly." Brown dwarfs are less slowly rotating body (eg. rotation lasts 500 days).
In contrast brown dwarf standing white dwarf rapidly rotating body about an axis which is confirmed by very fast orbits a brown dwarf is a star in the making that is in complete contrast with the outdated assertions and hypotheses. http://www.svemir...e-causal

I would assume that eventually the white dwarf is going to pull the brown dwarf completely unto itself, this is likely to have the results of an event somewhere between Nova and Supernova as it would be more mass than what a white dwarf would normally throw off in a nova, coming all at once, and yet it is not the same compact pass as another white dwarf so it is not the type 1a supernova either.

It may be this type of system is not all that uncommon, just harder to detect, and my be responsible for specific novae and nebulae types and configurations.

The brown dwarf in question, being tidally locked and having an orbital period of 78 minutes means that it is rotating MUCH faster than wduckss seems to think it is and so blows THAT theory clean out of the water.
