Description
The binary properties of old brown dwarfs are observed to be substantially different than in young clusters, with fewer companions and closer separations seen around older objects. Measuring the initial brown dwarf binary frequency is necessary to allow more realistic modelling for formation theories. Similarly, constraining binary properties at field ages is essential to understand the discrepancies observed and be able to predict the evolution and fate of binaries. In this talk, I will present results from an HST campaign compiled to look at the differences in the binary statistics as a function of age for the extreme low-mass end of the Initial Mass Function. Based on a Bayesian statistical analysis of companion population distributions, I will discuss the implications of observed disparities in substellar binary properties with age for formation and evolution models.
