    Discovery of the first wide L dwarf + giant binary system and eight other ultracool dwarfs in wide binaries
    We identify 806 ultracool dwarfs (of which 34 are newly discovered L dwarfs) from their Sloan Digital Sky Survey (SDSS) riz photometry and obtain proper motions...

    Discovery of the Massive Overcontact Binary VFTS352: Evidence for Enhanced Internal Mixing
    The contact phase expected to precede the coalescence of two massive stars is poorly characterized due to the paucity of observational constraints. Here we...
