However\, the binary statistics of the latest-type T and Y brown dwarfs are sparse and it is unclear wheth er the trends seen for their more massive counterparts hold for the very c oolest brown dwarfs. On the other hand\, young brown dwarfs appear to have different multiplicity properties than those observed in the older field population. Measuring and understanding these discrepancies is necessary t o allow more realistic modelling for formation theories and be able to pre dict the evolution and fate of binaries. In this talk\, I will present res ults from a campaign compiled to investigate the binary statistics as a fu nction of age for the extreme low-mass end of the Initial Mass Function. B ased on constraints from Bayesian statistical analyses\, I will discuss th e implications of the observed disparities for brown dwarf formation and e volution models.\n LOCATION:https://researchseminars.org/talk/CENTRA/24/ END:VEVENT END:VCALENDAR
