(a): eccentricity distribution of ejected brown dwarf binaries at 100 Myr. (b): eccentricity for ejected brown dwarf binaries at 100 Myr as a function of the mass ratio M_B/M_A. (c): eccentricity for ejected brown dwarf binaries at 100 Myr as a function of the total binary mass M_B+M_A. (d): eccentricity for ejected brown dwarf binaries at 100 Myr as a function of the semimajor axis a.
