Descripción
This paper discusses benchmark brown dwarfs in various environments, and
focuses on those in wide binary systems. We present a summary of the
recently discovered T dwarf population from the UKIDSS Large Area
Survey, and describe the constraints that it places on our knowledge of
the sub-stellar initial mass function. We also present some exciting
results from our ongoing search for wide companions to this sample, that
has so far revealed an M4-T8.5 binary system at ˜12 parsecs and
also the first ever Tdwarf-white dwarf binary system. The T dwarfs in
these binaries have their properties constrained by the primary object
and are thus benchmark objects that are already testing the predictions
of theoretical model atmospheres.
