    A coordinated X-ray and optical campaign of the nearest massive eclipsing binary, [delta] Orionis Aa. III. Analysis of optical photometric (MOST) and spectroscopic (ground based) variations 
    Pablo, Herbert; Richardson, Noel D.; Moffat, Anthony F. J.; Corcoran, Michael; Shenar, Tomer; Benvenuto, Omar; Fuller, Jim; Naze, Yael; Hoffman, Jennifer L.; Miroshnichenko, Anatoly; Guenther, David B. (American Astronomical Society, 2015-08-20)
    We report on both high-precision photometry from the Microvariability and Oscillations of Stars (MOST) space telescope and ground-based spectroscopy of the triple system [delta] Ori A, consisting of a binary O9.5II+early-B ...

    Spectroscopy, MOST photometry, and interferometry of MWC 314: is it an LBV or an interacting binary? 
    Richardson, Noel D.; Moffat, Anthony F. J.; Maltais–Tariant, Raphael; Pablo, Herbert; Gies, Douglas R.; Saio, Hideyuki; St-Louis, Nicole; Schaefer, Gail; Miroshnichenko, Anatoly S.; Farrington, Chris; Guenther, David B. (Oxford University Press, 2016)
    MWC 314 is a bright candidate luminous blue variable (LBV) that resides in a fairly close binary system, with an orbital period of 60.753 [plus or minus] 0.003 d. We observed MWC 314 with a combination of optical spectroscopy, ...
