"Filling the gap between stars and planets:
the
formation history of galactic brown dwarfs"
ABSTRACT: We present new strategies for the identification and
characterisation of benchmark brown dwarfs, with known ages and
metallicities, in the Galactic disk. We seek such objects in young
clusters and star-forming regions, and as companions to subgiants and
white dwarfs. We propose to use these benchmarks to construct an
empirical calibration scheme which will be used to constrain the disk
substellar initial mass function and brown dwarf formation history
from the unprecedentedly large samples of new brown dwarfs expected
from the UKIDSS Large Area and Galactic Cluster surveys.
