Description | We propose to observe the early X-ray emission of the ejecta of two novae in outburst, a classical or short-period recurrent nova, and a rarer symbiotic one (i.e., known to be a red giant binary). They will be observed when, with the Swift XRT, we establish that they are sufficiently luminous for high quality RGS spectra and that the central, luminous supersoft X-ray source does not outshine the ejecta yet. The X-ray spectra of nova winds probe the nova kinematics, its chemistry and connections with the phenomena observed at other wavelengths,including the intriguing gamma-ray emission. High resolution X-ray spectra of the outflowing material, without a major contribution yet of the central source, have seldom been obtained; we do need to broaden the sample to explore the complex physics. |

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. |
