Color–magnitude diagrams for very low-mass Hyades members. Single M and L stars in our survey are shown as gray circles while the two T dwarfs are shown at green stars. Tight binaries (≲05) are shown as pairs of filled and open red squares for primaries and secondaries, respectively. Wide companions detected in multiple bands in our adaptive optics images and in 2MASS images (in which case we use 2MASS photometry) are shown as blue and purple open squares, respectively. All candidate companions to very low-mass cluster members are labeled. Circled symbols indicate companions shown to be unrelated background stars by their motion relative to their respective primaries. The solid line represents the 600 Myr NextGen isochrone down to a mass of 0.075 M_⊙ while the dashed, dotted and dot-dashed curves represent the DUSTY, COND and BT-Settl models over the 0.03–0.07 M_⊙ range. Note that the COND models predict J − K colors that are markedly bluer than any known very-low mass cluster member.
