Scientific paper

We report on a 32 ksec ASCA observation of the eclipsing cataclysmic variable XY Ari. The ASCA data are best fit by a power law indicating that material with a range of temperatures contributes to the total emission. The Fe line behavior is complex and varies with orbital phase. A 6.55 keV line with an equivalent width of ~220 eV is detected in the phase range ~0.10-0.30. A 6.4 keV line with an equivalent width of ~400 eV is detected in the range ~0.30-0.50. Upper limits on the equivalent widths of ~100-150 eV exist on both lines in the 0.50-0.90 phase range.
