EXOSAT observations of the magnetic binary system E 1114+182.

Abstract

In this short note we present EXOSAT X-ray light curves of the magnetic binary system E1114+182 for two epochs. The epochs of the eclipse minima follow closely the ephemeris of Biermann et al., demonstrating that the period has not changed since the first observation with the EINSTEIN X-ray observatory in 1979. We compare the new X-ray llght curves with the earlier data, noting in particular possible weak X-ray emission from the secondary magnetic pole.
