First UV spectrum of the AM Herculis star RX J1940.1-1025.

FRIEDRICH S., STAUBERT R. and LA DOUS C.

Abstract (from CDS):

We present the first UV spectrum of the polar RX J1940.1-1025, taken with the IUE satellite in the wavelength range between 1190A to 1950A. The phase averaged spectrum shows strong emission lines of CIV (1550A), NV (1240A), SiIV (1397A) and HeII (1640A) which are typical for AM Her stars. The line ratios of NV/SiIV and NV/CIV, and the continuum flux are also consistent with those found in other polars. The slope of the UV continuum can be attributed to the white dwarf which would have a temperature in the range between 15000K and 21000K. Equivalent widths of the emission lines suggest an inclination angle below 60° in agreement with results from optical and X-ray observations.
