| Description | A recently-discovered intermediate polar, CTCV J2056-3014, has the shortest spin period (29.6 sec) among all CVs and white dwarfs. Fast-spinning CVs are extremely rare and unique as manifested by AR Sco (the white dwarf pulsar) and AE Aqr which spins down via the propeller effect. The proposed XMM + NuSTAR observation will allow us to fully explore the X-ray spectral and timing properties of this remarkable CV. Our primary goals are (1) determining its white dwarf mass accurately for testing the stability condition of fast-spinning WDs, (2) detecting a weak, neutral Fe K-alpha line as a signature of tall accretion column, and (3) search for non-thermal X-ray pulsation such as found from AR Sco. |

| 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. |
