A Substellar Companion to the Dusty Pleiades Star HD 23514
Rodriguez_David.pdf (563.0Kb)Abstract
With adaptive optics imaging at Keck observatory, we have discovered a sub-
stellar companion to the F6 Pleiades star HD 23514, one of the dustiest main-
sequence stars known to date (LIR=L 2%). This is one of the rst brown
dwarfs discovered as a companion to a star in the Pleiades. The 0.06 M late-M
secondary has a projected separation of 360 AU. The scarcity of substellar com-
panions to stellar primaries in the Pleiades combined with the extremely dusty
environment make this a unique system to study.
