We present H (1.65 \mu; m) and K (2.2 \mu; m) sub-AU angular size measurements for a series of Vega-like stars observed at the Palomar Testbed Interferometer (PTI). These data are part of a long term observational program using PTI to characterize the sub-AU morphology of Vega-like stars. In each case, PTI has resolved the near-infrared emission from these sources. We present the results and discuss the possible emission sources which contribute to measured visibilities.
