Description | The recurrent nova T Pyx is an intriguing accreting binary because of its prolific outburst behaviour, large quiescent luminosity, short orbital period and rapid orbital period evolution. An unusually high mass-accretion rate is implied and it has even been proposed continuous nuclear burning may occur on the accreting white dwarf. Systems with a massive white dwarf accreting at high rates are potential Type Ia progenitors. Our proposed XMM observations will establish if a wind-driven supersoft source scenario is indeed at play in T Pyx, or whether its X-ray luminosity demands an alternative evolutionary interpretation. These observations will thus have important implications for novae, super-soft sources and cataclysmic variable evolution. |

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. |
