With adaptive optics imaging at Keck observatory, we have discovered a
substellar companion to the F6 Pleiades star HD 23514, one of the dustiest
main-sequence stars known to date (L_{IR}/L_{*}~2%). This is one of the first
brown dwarfs discovered as a companion to a star in the Pleiades. The 0.06
M$_\odot$ late-M secondary has a projected separation of ~360 AU. The scarcity
of substellar companions to stellar primaries in the Pleiades combined with the
extremely dusty environment make this a unique system to study.
