SUMMARY OF SEQUENCE NUMBER 300009
Title: SUPER-SOFT X-RAY SOURCES
Observer: MURRAY
Subject Category: WD Binaries and CVs
Seq: 300009 ObsId: 00084
Long-term Plan bin: no LTS bin
ABSTRACT
The nature of a large subset of luminous supersoft X-ray sources (SSSs) has not yet been established. Although they are thought to be white dwarfs steadily burning accreted matter, there is no definitive evidence that this picture is correct: in particular we do not have direct evidence that any of the systems contain an accreting white dwarf. The observations we propose will provide good spectral information for all of the SSSs that are candidates for the nuclear-burning white dwarf model. We will be able to extract values of the temperature, luminosity and N_H, and to see evidence of absorption edges that may be associated with the white dwarf's atmosphere.
