The eclipsing binary AI Phoenicis - New results based on an improved light curve analysis program
Eugene F. Milone, C. R. Stagg, Robert L. Kurucz · The Astrophysical Journal Supplement Series · 1992
A revised atmospheres option based on the model developed by Kurucz (1979) together with empirical correction factors are used to model the parameters of AI Phe with the program of Wilson and Devinney (1971), employing a single temperature to parameterize all light curves from the UV to the IR, with better agreement with observation than previous attempts applying this mode. Improved precision in coupled luminosity-temperature determinations is obtained, especially in fitting to the ground-based UV. The present fittings to IUE data suggest nonlinear limb darkening for the primary component. The limb darkening of the hotter component in the far UV as it undergoes total eclipse is investigated and compared with Kurucz models.
