| Abstract: |
The short interval between successive outbursts of RS Oph strongly suggests that it has a high-mass white dwarf accreting at a high rate. This, in turn, suggests the possibility of prominent X-ray emission from RS Oph in quiescence. However, archival quiescent X-ray observations of RS Oph show it to be a modest soft X-ray source, but not a strong 2–10 keV X-ray source. In this aspect, RS Oph differs markedly from T CrB. We speculate on the possible mechanisms that could significantly suppress the 2–10 keV X-ray emission in RS Oph. |
