[63.10] PTI Observations of 89 Her

M. R. Swain, G. T. Van Belle (JPL), R. L. Akeson (IPAC)

We report on observations of the star 89 Her with the Palomar Testbed Interferometer (PTI). Our observations in the H and K bands suggest the presence of a circumstellar dust shell. We discuss the observations in the context of simple models for 89 Her.
