Query: Cloud Properties of Brown Dwarf Binaries Across the L/T Transition   We present a new suite of atmosphere models with flexible cloud parameters to
investigate the effects of clouds on brown dwarfs across the L/T transition. We
fit these models to a sample of 13 objects with well-known masses, distances,
and spectral types spanning L3-T5. Our modelling is guided by
spatially-resolved photometry from the Hubble Space Telescope and the W. M.
Keck Telescopes covering visible to near-infrared wavelengths. We find that,
with appropriate cloud parameters, the data can be fit well by atmospheric
models with temperature and surface gravity in agreement with the predictions
of evolutionary models. We see a clear trend in the cloud parameters with
spectral type, with earlier-type objects exhibiting higher-altitude clouds with
smaller grains (0.25-0.50 micron) and later-type objects being better fit with
deeper clouds and larger grains ($\geq$1 micron). Our results confirm previous
work that suggests L dwarfs are dominated by submicron particles, whereas T
dwarfs have larger particle sizes.
