Symbiotics in transition: X-rays from AG Peg and T CrB

We propose to carry out EPIC imaging spectroscopy of two symbiotic stars, AP Pegand T CrB, that show considerable recent activity. The EPIC data will providethe first Xray spectrum of AG Peg with a very good quality allowing us to studyits Xray properties in detail, especially, in the current transition of thisobject from symbiotic nova to a classical symbiotic system. Similarly, we willobtain a good quality spectrum of T CrB in its superactive state the object hasentered in 2015. This will be very useful to confront its Xray propertiesbetween quiescent and superactive states. The EPIC observations will reveal ifshorttime (hours) Xray variability (flickering) is present in both objects. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
