Brown Dwarf Hits Record Low

astroengine writes "The Keck II infrared telescope on Mauna Kea, Hawaii, has spotted what appears to be the coldest brown dwarf ever detected. Astronomers from the University of Hawaii have managed to constrain its temperature to just shy of 100 degrees Celsius. The object is part of a brown dwarf binary system and is estimated to be 6-15 times the mass of Jupiter. This is an exciting object as it could belong to a so-far theoretical 'Y' class of brown dwarf, a classification that makes objects like this cool example more planet-like than star-like."

"Brown" Dwarf?

Lister better get back to work. The Dwarf should be RED!

Coldest brown dwarf? Not even close.

The coldest brown dwarf ever was that elf in Bad Santa [imdb.com].

Did they make this brown dwarf?

The first sentence of the summary says they "spotted" the brown dwarf. This implies that it was out there and they observed it. The second sentence says that they managed to "constrain" its temperature. This implies that they have control over its temperature. I think that if they have found a way to control the temperature of a brown dwarf (or any other star) that is bigger news than that this is the coolest brown dwarf they have found.
