I find that somewhat disappointing...

Look on the bright side: There's a smaller chance of a brown dwarf infiltrating the Solar system and messing things up as we all go around the Great Milky Way Merry-Go-Round. Very Happy

Not so surprising result, actually. If my memory serves, the detected number of young brown dwarfs in star clusters is much less than the number of stars?

BTW, this result of course does not exclude the possibility that there are rogue planets between the Sun and Alpha Centauri, masses up to several Jupiters.

Not related to exoplanets or brown dwarfs, but definitely worth mentioning:

Bonanza of newfound supermassive black holes and extreme galaxies called hot DOGs, or dust-obscured galaxies.

A 0.520 Jupiter mass object with a temperature 250400 K. May be either a brown dwarf or a free-floating planet.

The Closest Star System Found in a Century
http://science.psu.edu/news-and-events/2013-news/Luhman3-2013

WISE J104915.57-531906.1, a brown dwarf binary at 2.00.15 parsecs. Primary is L81, secondary near the L/T transition.

The best estimate of the distance (ignoring the error bars) puts the binary slightly further away than Barnard's Star.

More on WISE J104915.57-531906.1
http://arxiv.org/abs/1303.5345

Offers also some more memorable designations for the system: "Luhman 16" (its preliminary WDS designation) or maybe "Luhman-WISE 1".

Why not Luhman's Star, like other nearby stars named after the people who discovered or recognized them?
