    Light2: A Light-Curve Modeling Program

    Since 1968 when the first descriptions of computer codes capable of modeling eclipsing binary light curves appeared in the literature (Lucy 1968, Hill and Hutchings 1970, Wilson and Devinney 1971, Wood 1971, 1...

    Investigations of CP and Normal Stars with Coadded Dominion Astrophysical Observatory Spectrograms

    We describe the procedures developed at the Dominion Astrophysical Observatory to coadd high dispersion coude spectrograms and thus increase the signal-to-noise ratio in photographic data. These techniques can...

    Studies of O-F5 Stars at the Galactic Poles

    We report progress on a spectroscopic and photometric programme devoted to the study of the dynamics of O-F5 stars within 15° of the North and South Galactic Poles. The aims of the programme are to test dynami...

    The Subdwarf Eclipsing Binary LB3459 (AA DOR)

    A review was presented of the currently available observational data on this evolved system, namely, uvby photometry (Kilkenny et al. 1978; paper II) radial velocities (Kilkenny et al. 1981; paper III) and a n...

    Studies of A and F Stars in the Region of the North Galactic Pole

    A short account was given of results recently published (Hill et al. 1976; Hilditch et al. 1976a, b) of a spectroscopic and photometric study of 310 A0-F8 stars within 15° of the north galactic pole. Using these ...

    The synthesis of close-binary light curves IV: An application to TX ursae majoris and MR Cygni

    A full description is given of the theory used in light curve synthesis, for binary stars showing various degrees of interaction. For strongly interacting pairs, an iterative mutual heating calculation is intr...
