Title V407 Cyg: A new laboratory for studying accretion and novae in symbiotic stars


DOI https://doi.org/10.5270/esa-gfhf7rc
Author Dr Thomas Nelson
Description We propose a 100 ks observation of the V407 Cyg, a symbiotic star which recently experienced its first recorded nova outburst. A new X-ray observation of the system in quiescence will allow us to establish the timescales over which accretion is re-established after the nova outburst, and if it has, the rate at which material is accreted by the white dwarf. We will also study the long term evolution of the nova ejecta. Characterizing the accretion process and interaction of the ejecta with the companion wind is a key part of understanding type Ia supernovae like SN 2002ic, which exhibit evidence of strong circumstellar interaction.

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.
