Fig. 2


Top left: I − (RI); top right: I − (IJ); bottom left: I − (IK); and bottom right: J − (JK) colour-magnitude diagrams of optically selected candidates (points) from the TLS and 2MASS/UKIDSS surveys; the propermotion candidates are indicated by filled circles. In all CMDs, we show 625 Myr BT-Settl isochrones shifted to the distance of the Hyades cluster (mM = 3.33) as solid lines. The vertical line labelled with stellar mass (M ) is the mass scale according to this model. The two dashed lines outline the selection area (see text). The upper horizontal line at I = 18.1 shows the stellar/substellar boundary and the lower line indicates the lithium burning limit. The BT-Settl isochrone in the J − (JK) CMD agrees well with the colour indices of the faintest member candidates.
