Questions

   Observing_Description: We will observe each of four Hyades cluster members
                          once during Cycle 5 to confirm duplicity or 
                          substantiate rapid orbital motion.

Abstract:               We propose to use FGS in the TRANS mode to observe, at 
                        high angular resolution, four Hyades cluster members 
                        either to confirm a very faint companion or substantiate
                        rapid orbital motion.  These Hyades binaries are of
                        particular importance because each probably contains 
                        either a very low-mass main sequence or a degenerate
                        component.
