Polarimetry Probes Brown Dwarf Clouds which shows signs of cloud bands similar to those seen on Jupiter Currently Luhman 16 is the third-closest-known star/brown-dwarf system to the Sun after the triple Alpha Centauri system (4.37 ly) and Barnard's Star (5.98 ly), Luhman 16A is p art of a binary system (Luhman 16) containing a second brown dwarf, Luhman 16B. This pair of brown dwarfs Luhman 16A and Luhman 16B orbit each other.

Luhman 16B shows no sign of stationary cloud bands, instead showing evidence of more irregular, patchy clouds Polarimetry  is the measurement and interpretation of the  polarization  of  transverse waves , most notably  electromagnetic waves , such as radio or light waves.
