Scientific paper

We report on near-IR interferometric observations of the double-lined pre-main sequence (PMS) binary system DQ Tau. With these observations and the previous spectroscopic orbit & analysis by Mathieu et al 1997 we have estimated a preliminary visual orbit of the DQ Tau system. DQ Tau exhibits a significant near-IR excess, so modeling our interferometric data requires the inclusion of near-IR light from an 'excess' source. Remarkably this excess source appears compact in our data, similar in physical scale to the binary itself, rather than a significantly larger circumbinary disk. This compact emission appears to support arguments by Mathieu et al 1997 and Carr et al 2001 that there is significant near-IR flux from warm gas and dust near the DQ Tau binary, and that dynamical clearing expected in a binary system has not been completely successful in dispersing this material.
