| Abstract: | This project is part of a world wide cooperation aimed at investigating properties of white dwarf stars to determine their constitution and evolution. The project is based on two recent developments:-The first is the discovery, of pulsational instabilities in some white dwarf stars, giving rise to non-radial pulsations which can be observed as flux modulations with low amplitude.-The second is to study the mass transfer between interacting binary white dwarf stars, which transports processed material from the interior of the donating star to the accretor. We present a study of four interacting binary white dwarf systems based on IUE spectra.Paper presented at the 11th European Regional Astronomical Meetings of the IAU on  New Windows to the Universe , held 3–8 July, 1989, Tenerife Canary Islands, Spain. |
