| Description | We propose to carry out EPIC imaging spectroscopy of two symbiotic stars, AP Peg and T CrB, that show considerable recent activity. The EPIC data will provide the first X-ray spectrum of AG Peg with a very good quality allowing us to study its X-ray properties in detail, especially, in the current transition of this object from symbiotic nova to a classical symbiotic system. Similarly, we will obtain a good quality spectrum of T CrB in its super-active state the object has entered in 2015. This will be very useful to confront its X-ray properties between quiescent and super-active states. The EPIC observations will reveal if short-time (hours) X-ray variability (flickering) is present in both objects. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
