Scientific paper

The pre-main-sequence binary T Tauri was observed in 1991 September using a simultaneous combination of the VLA and a four-antenna VLBI array operating at a wavelength of 18 cm. Strong circular polarization was detected in the VLA measurements, and there was evidence for variations in both circular polarization V and total intensity I on time scales of 1 hr. VLBI measurements of T Tauri taken in parallel failed to detect any compact flux density, despite having sufficient sensitivity to measure fringe visibilities as faint as 15 percent of the total flux density from the source. If the radiation from T Tau resembles that from other stellar radio sources in circular polarization fraction, the VLBI measurements imply a lower limit on the size of unpolarized radiation of about 1 AU or 70 stellar radii.
