A coordinated x-ray and optical campaign of the nearest massive eclipsing binary, δ orionis Aa. III. Analysis of optical photometric (MOST) and spectroscopic (ground-based) variations

We report on both high-precision photometry from the <i>Microvariability and Oscillations of Stars</i> (MOST) space telescope and ground-based spectroscopy of the triple system δ Ori A, consisting of a binary O9.5II+early-B (Aa1 and Aa2) with P = 5.7 days, and a more distant tertiary (O9...
