High-amplitude variations during early SSS phase in novae

Extensive Swift Xray monitoring of novae has revealed unexpected variability onthe rise to Xray maximum in all novae with extensive monitoring but the causeremains elusive. Only a long XMM exposure during this early variability phaseallows RGS time evolution studies to fully investigate possible causes such asvariations in absorption, intrinsic brightness, or temperature. We propose XMMtime totalling 145ks for two triggered observations\\: a 100ks observationtriggered during the early Xray variability phase with <2d response and asecond 45ks observation with >1week response time during the later SSS phase tofind what has changed to make the variations stop. We will search bothobservations for transient shortperiod oscillations. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
