  • An investigation of molecular opacities for late-type stars 

    Sharp, Christopher Martin (University of St Andrews, 1981) - Thesis
    This work investigates molecular opacities under conditions appropriate to the atmospheres of late-type stars. Given a specified initial abundance of the chemical elements, the equations of atomic ionization and molecular ...
  • The pulsation of Delta Scuti stars 

    Milligan, Helen (University of St Andrews, 1989) - Thesis
    A theoretical study of the pulsation of Delta Scuti stars is presented. A modified Henyey code is used to produce a grid of evolutionary models of population I composition, spanning the area of the Instability Strip ...
  • A theoretical study of population II Cepheids with periods in the range 10-20 days 

    Bridger, Alan (University of St Andrews, 1984) - Thesis
    A theoretical study of population II variables with periods in the range 10 - 20 days (W Virginis variables) is presented. A modified hydrodynamic Christy code is used in conjunction with the Carson opacities, in ...
  • A theoretical study of the R. Coronae Borealis group of variable stars 

    Willingale, Graham A. P. (University of St Andrews, 1989) - Thesis
    A theoretical study of the R Coronae Borealis group of variables is presented. A modified Christy code is used for the non-linear calculations and Dr Worrell's codes are used for the linear calculations. These codes are ...
