000002026 520__ $$aθ2 Tau is a well-detached, "single-lined" Hyades binary consisting of two midtype A stars which both lie in the lower Cepheid instability strip. As a matter of fact, component A is a classical δ Scuti star showing a complex pattern of pulsations while component B might also be a δ Scuti pulsator (Breger et al. 2002). We acquired new high-resolution, high signal-to-noise spectra in order to determine accurate properties for the components of this system. Combining both spectroscopy and long-baseline optical interferometry, we were able to derive the orbital parallax and the component masses with unprecedented accuracy. Such constraints on the physical properties of the components are needed for a deep understanding of the pulsation physics. We also believe that θ2 Tau is an appropriate target to explore, in an empirical way, the possible interaction(s) between pulsation on the one hand and rotation and binarity on the other hand.
