We report on interferometric and radial-velocity observations of the double-lined 51-d period binary ( A ) component of the quadruple pre-main sequence ( PMS ) system V773 Tau . With these observations we have estimated preliminary visual and physical orbits of the V773 Tau A subsystem . Among other parameters , our orbit model includes an inclination of 66.0 \pm 2.4 deg , and allows us to infer the component dynamical masses and system distance . In particular we find component masses of 1.54 \pm 0.14 and 1.332 \pm 0.097 M _ { \sun } for the Aa ( primary ) and Ab ( secondary ) components respectively . Our modeling of the subsystem component spectral energy distributions finds temperatures and luminosities consistent with previous studies , and coupled with the component mass estimates allows for comparison with PMS stellar models in the intermediate-mass range . We compare V773 Tau A component properties with several popular solar-composition models for intermediate-mass PMS stars . All models predict masses consistent to within 2-sigma of the dynamically determined values , though some models predict values that are more consistent than others .
