Abstract: |
We present the progress of an ongoing program to obtain and understand moderate
resolution (R ≥ 1500) near-infrared spectroscopy for all CV subtypes. In
general, pre-CV, magnetic, and short period systems appear normal and do not
harbour any surprises. Long period systems, however, show weak or absent
K-band CO lines which we interpret as a deficit of C. To fully assess these
data, we compute synthetic spectra using either PHOENIX or MOOG at varying
abundance patterns. We present preliminary results of this observation and
modelling program. |
