Abstract
Updated VIJHK photometry is presented for 12 stars from Leggett & Hawkins, along with trigonometric parallaxes and proper motions for three of the stars, that are candidate brown dwarfs in the Hyades. The three stars with parallaxes are found to lie well beyond the Hyades cluster and to fall 3–4 mag above the main sequence, indicating that they are pre–main-sequence objects. These results illustrate the problem that contaminating field stars pose for attempts to identify rare objects such as brown dwarfs as physical members of clusters.Keywords
