Abstract:
Multiplicity of stars within clusters is a well-studied phenomenon.
However, recent survey work done on the Hyades by Mason et al.
[1993AJ....105..220M 1993AJ....105..220M] would seem to indicate that even in the most
often studied clusters, there may be binaries yet undiscovered. In
order to expand the sample of cluster binaries with potentially
short-period visual orbits, a speckle survey of 45 Pleiades, 54
Praesepe, and 22 IC 4665 bright stars (V < 10) for possible
multiplicity was conducted at the KPNO 4 m Mayall telescope between
1987 October and 1991 November. Of these, three new binaries have been
discovered: one in the Pleiades where the new component may be
spectroscopic, another in Praesepe which has been confirmed from
examinations of archival observations and also has been resolved by
occultation, and the third in IC 4665. Continued study of these new
binary stars could further refine the cluster distance moduli as well
as the cluster mass-luminosity relations.
