Abstract (from CDS):

We have attempted to resolve the system containing the Cepheid V1334 Cyg (=ADS 14859) using both the Faint Object Camera (FOC) and the Fine Guidance Sensor (FGS) on the Hubble Space Telescope, and also using ground-based speckle interferometry with 4 m class instruments. None of these approaches was successful, leading to upper limits of approximately 20 mas (depending on the magnitude difference between the stars). We discuss constraints this places on a possible wide orbit as a guide to future observations.
