EXOSAT light curves of E2003+225


X-ray light curves of E2003+225

Folded soft X-ray light curves of the AM Her system E2003+223. On top, the usually observed form of the light curve. It is complex and has a total eclipse at phase 0.35 due to the gas stream from the companion passing through the line of sight. Below, in a second observation two months later, the light curve changed completely. It is easily understood that this is due to a single emission region on the rotating white dwarf. The eclipse by the gas stream is again visible, but now shifted to phase 0.4 suggesting a major change in the accretion geometry.
