A Duplicity Survey the Hyades Cluster Mason, Brian D. ; McAlister, Harold A. ; Hartkopf, William I. ; Bagnuolo, William G., Jr. Abstract The Hyades cluster is the nearest open cluster to the solar system, and its distance has long been a contentious issue. In order to expand the sample of Hyades binaries with potentially short-period visual orbits, a speckle survey of 153 bright Hyades stars for possible multiplicity was conducted at the KPNO 4 m Mayall telescope on November 23-27, 1991. Of these, one is graded as a suspected new binary, three are graded as possible new binaries, and three are graded as definite new binaries, one of which has been confirmed from examination of an archival observation from 1989. Of these seven new visual resolutions, six have possible spectroscopic components, two of which are probably the objects observed here, three certainly are not, and one may or may not be the component observed.
