Archival HST and IUE study of the dwarf novae AH Her and CM Del: Exposed white dwarfs?

Abstract:

We have analyzed HST archival and IUE NEWSIPS archival SWP spectra of the dwarf novae CM Del and AH Her obtained when AAVSO light curve data indicated the occurrence of dwarf nova quiescence. HST archival outburst data for AH Her is examined as well. We have computed synthetic, high gravity spectra in LTE with solar composition using TLUSTY195 and SYNSPEC42 and carried out fits of these models to the far UV continuum and narrow absorption line spectra. For CM Del, we find that the far UV spec...
