Movie of ultracool binary orbits shown during my talk at Cool Stars 18.  Colors of components correspond to their spectral types: late-M and early-L dwarfs are orange; dusty later type L dwarfs are pinkish red; and methane dominated T dwarfs are blue.


Keck Observatory Cosmic Matters article on things we’ve learned from brown dwarf binary orbits.  Press release on the discovery of a very cool binary CFBDSIR1458.



















Artist conception of a Y dwarf.  Our parallaxes for Y dwarfs showed that they are indeed the coldest known brown dwarfs, but we also found that properties like convective mixing, surface gravity, or elemental abundances may play as important a role as temperature in driving the atmospheric chemistry of these possibly planetary-mass brown dwarfs.
