Description

Observations of the serendipitous EXOSAT source EXO 023432-5232.3 are reported which confirm that the object is an AM Herculis type binary and show the presence of eclipses by the companion star. From high-speed photometry of the eclipses we deduce that the cyclotron emission region is less than one seventh the size of the white dwarf. From the infrared magnitude of the secondary a distance of 430 pc is deduced. We discuss constraints on the system geometry. (author)
