We present the data from a unique observational study of Spica, a binary system with a primary component of β Cephei type. We exploit simultaneous high-resolution spectroscopic observations and high-precision photometry obtained by the MOST satellite. By disentangling the spectra of this binary, we get an accurate determination of the orbit. Future work includes a full seismic analysis of the system.
