The Photometric Properties of L and T Dwarf Binaries

After years of study, the evolution and atmospheric properties of brown dwarfs remain challenging to understand. Recent studies using volume-limited samples have shown the evolution of single L and T dwarfs and unresolved binaries as they move through the L/T transition. We investigate the photometric evolution of resolved brown dwarf binary components using this volume-limited sample and provide evidence to confirm four possible binary candidates. We also provide a new binary fraction for L0-T8 dwarfs.
