The detection of the donor star in IY UMa.
Monthly Notices of the Royal Astronomical Society, 334(3) pp. 699–704.
We present the results of a search for the donor star in the high-inclination SU UMa type cataclysmic variable IY UMa. We detect absorption features in the near infrared consistent with an M type dwarf donor star. Using the skew mapping technique to exploit the velocity information provided by the 8183–8194 Å Na i absorption doublet, we locate the absorption at the expected donor velocity of IY UMa.
