Conclusions
Discovering VLM and BD companions is HARD
secondary MF is NOT randomly drawn from IMF
dynamical few-body decay model w/ two-step IMF can reproduce obsvd. trends in BF & MR
predict a BD companion frequency of < 1%
BUT: GJ 86 and his friends are still not alone!
Gliese catalog stars should have about 30 BD companions, 5 are discovered....
