Query: Quantifying the Carbon Abundances in the Secondary Stars of SS Cygni, RU
  Pegasi, and GK Persei   We use a modified version of MOOG to generate large grids of synthetic
spectra in an attempt to derive quantitative abundances for three CVs (GK Per,
RU Peg, and SS Cyg) by comparing the models to moderate resolution (R $\sim$
25,000) $K$-band spectra obtained with NIRSPEC on Keck. For each of the three
systems we find solar, or slightly sub-solar values for [Fe/H], but significant
deficits of carbon: for SS Cyg we find [C/Fe] = $-$0.50, for RU Peg [C/Fe] =
$-$0.75, and for GK Per [C/Fe] = $-$1.00. We show that it is possible to use
lower resolution (R $\sim$ 2,000) spectra to quantify carbon deficits. We
examine realistic veiling scenarios and find that emission from H I or CO
cannot reproduce the observations.
