Query: Substellar Hyades Candidates from the UKIRT Hemisphere Survey   We have used data from the UKIRT Hemisphere Survey (UHS) to search for
substellar members of the Hyades cluster. Our search recovered several known
substellar Hyades members, and two known brown dwarfs that we suggest may be
members based on a new kinematic analysis. We uncovered thirteen new substellar
Hyades candidates, and obtained near-infrared follow-up spectroscopy of each
with IRTF/SpeX. Six candidates with spectral types between M7 and L0 are ruled
out as potential members based on their photometric distances ($\gtrsim$100
pc). The remaining seven candidates, with spectral types between L5 and T4, are
all potential Hyades members, with five showing strong membership probabilities
based on BANYAN $\Sigma$ and a convergent point analysis. Distances and radial
velocities are still needed to confirm Hyades membership. If confirmed, these
would be some of the lowest mass free-floating members of the Hyades yet known,
with masses as low as $\sim$30 $M_{\rm Jup}$. An analysis of all known
substellar Hyades candidates shows evidence that the full extent of the Hyades
has yet to be probed for low-mass members, and more would likely be recovered
with deeper photometric and astrometric investigations.
