Far-ultraviolet spectral analysis of the prototype nova-like variable VY Sculptoris from the high state to the low state.

HAMILTON R.T. and SION E.M.

Abstract (from CDS):

The prototype nova-like variable VY Sculptoris was observed by the IUE during four different optical brightness states of the system. The far-ultraviolet (FUV) flux level from the highest state to the lowest state declines by a factor of 28. We have carried out model accretion disk and white dwarf atmosphere fitting to the spectra. The corresponding accretion rates range from at the highest FUV flux level down to at the lowest flux level. We report tentative evidence for the detection of the underlying white dwarf with in the spectrum with the lowest flux level.
