    • Accurate astrophysical parameters for algol-type binary stars 

      Maxted, P. F. L. (University of St Andrews, 1995) - Thesis
      We present new, accurate astrophysical parameters for both components of the six short-period Algol-type binary stars RZ Cas, AT Peg, TX UMa, AF Gem, RU UMi and HU Tau. The accuracy of the astrophysical parameters is ensured ...

    • Multicolour photometry of Mira variables 

      Kelly, B. D. (University of St Andrews, 1977) - Thesis
      In Part 1, a background to the project is provided by summarizing the general properties of Miras. A section is devoted to describing pulsating variables from a theoretical viewpoint, and this is followed by a discussion ...

    • A spectroscopic and photometric investigation of the extreme helium-rich star HD 168476 

      Walker, H. J. (University of St Andrews, 1979) - Thesis
      Spectra were obtained from several sources for a fine abundance analysis of the extreme helium-rich star HD 168476. The atmospheric parameters are found using theoretical models and abundances determined for the ions ...

    • Studies of low-mass interacting binary stars 

      Rainger, Paul P. (University of St Andrews, 1990) - Thesis
      Spectroscopic and photometric observations of eight contact/near-contact binaries are presented and analysed. Spectroscopic observations were obtained at 4200 Å (radial velocity spectra) and 6563 Å (hydrogen-alpha line ...

    • Southern hemisphere early-type stars at intermediate and high galactic latitudes 

      Kilkenny, David (University of St Andrews, 1973) - Thesis
      A survey of early-type stars at intermediate galactic latitudes was carried out in the southern hemisphere winters of 1970 and 1971. The observing programme was limited to negative declinations and covered a range in right ...
