EUV and FUV observations of cataclysmic variables

Recent results from a continuing investigation of cataclysmic variables in the 500 to 1700 A region with the Voyager ultraviolet spectrometers are presented. Observations of outbursts show a substantial delay (of about 0.5 day) in the rise to maximum in the FUV (912-1200 A) with respect to optical w...

Zusammenfassung:Recent results from a continuing investigation of cataclysmic variables in the 500 to 1700 A region with the Voyager ultraviolet spectrometers are presented. Observations of outbursts show a substantial delay (of about 0.5 day) in the rise to maximum in the FUV (912-1200 A) with respect to optical wavelengths. Both FUV and optical light decline simultaneously. Flux distributions show a significant flattening in the FUV and with the possible exception of CPD-48 1577 no EUV flux has been observed in any cataclysmic variable. CPD-48 1577 shows a marginal, 2 sigma, EUV flux.
