The brown dwarfs will be warmer than expected. Just as Jupiter is warmer than expected.

I'm betting brown dwarfs are as common as M-class stars, maybe even more common. I think we will learn that there are a lot more brown dwarfs and planemos out there than previously thought.

Figuring mass is sometimes a lot easier, and something large doesn't always have a lot of mass. There is just something deep down inside me, telling me there is a lot more to brown dwarfs than we know or figure. Especially when there are two in close proximity. I understand the theories, yet something still isn't right. Hopefully some day soon, we will learn a lot more about these objects. Hard to say sometimes just how large something is.

The more massive ones might actually be smaller, due to gravitational compression, and the lack of outward pressure from the fusion process. They are probably about the size of Jupiter.

Have they not taken into account the wobble in the orbit, or possibly the central point to consider a binary object? Based on this logic, we could find a binary system like pluto and charon, say that it has a total combined mass of 15% earth and instantly draw a conclusion of 7.5% each without even needing a measurement other than the orbit...Im highly skeptical So let me get this straight…judging by this method and the results displayed in the article…whatever % the binary system weighs compared to the mass of the sun, they split it down the middle?
