AA Dor: Animation I

Left panels
Top: View onto the close, eclipsing, post common-envelope binary system AA Dor, that consists of a sdOB-type primary star and an unseen low-mass companion, from the top and from the side (as seen from Earth, i = 89.21 degrees).
Bottom: Normalized synthetic lightcurve

Right panels
Phase-dependent spectral variation of the He II 4686Å line profile. Our UVES spectra (bottom, smoothed by a Gaussian of 0.05Å FWHM) is compared with the synthetic spectrum (top).

AA Dor: Animation II

Top: View onto the binary system AA Dor from the side (as seen from Earth, i = 89.21 degrees). The illuminated part of the cool companion is shown.
Bottom: Phase-dependent synthetic spectrum around Hβ
