| Abstract: |
We have obtained simultaneous IJHK, time series spectroscopy (R ~1200) of five eclipsing dwarf novae in quiescence. The spectra show strong, double-peaked emission lines of H I and He I and absorption lines from the mass donor star. Trailed spectrograms of the strong Paschen and Brackett lines of H I and of He I in IP Peg show the primary eclipse of the accretion disk as well as a second reduction in line EW seen during the phases of secondary eclipse. The data are being used to explore the structures and optical depths of accretion disks in quiescent DN. |
