I think it's supposed to be 1200 years, even though at that distance, a 25 Jupiter Mass planet/brown dwarf would have an orbital period of 1533 years.

Well, the lower 1 sigma margin of error is within the planetary regime (I assume they meant -12, as opposed to -120, which would place it into the Warp Drive material regime).

Unless I've missed an end-of-line hyphenation somewhere, it doesn't even mention the word "planet", and the abstract states it probably formed star-like and thus qualifies as a brown dwarf.
