Brown-Dwarf planets question

[Puke]

i believe that these are actually brown dwarf stars, but its really ambigous. I think they were all theory untill we found one recently (Last couple years).

well, they are big things that are sometimes found orbiting stars, and radiate dim red light. sometimes they have really bright flare-ups.

but the one(s?) we found are suposedly cold, and give off surface heat as they slowly contract. I guess we know they are cold because they have elements in them (found through the spectrograph of the heat they give off) that stars do not.

right, so we found one about 75* jupiters mass, or 8% of our sun. to ignite into a sun, you have to be about 80* jupiters mass. the one we found, we think is about 1300 degrees (dont know in what unit of measure, sorry) compared to our sun, which can be up to 8000 degrees. they dont have a corona, but they do have magnetic fields. I think we saw one giving off x-ray flares.
