Planetary-mass binary 2MASS J11193254-1137466

The L-dwarf 2MASS J1119-1137 turns out to be a planetary-mass binary. Assuming membership of the TW Hydrae association, the masses of each component are estimated at 3.7^+1.2_-0.9 Jupiter masses, assuming the system is a young field binary then the masses increase to 9.2^+2.3_-1.9 and 9.0^+2.4_-1.9 Jupiter masses for the primary and secondary respectively. Binary projected separation is 3.6±0.9 AU.
