Description High-resolution X-ray spectra of novae in the Super Soft Source (SSS) phase are
extremely complex since the ejecta are clumpy and asymmetric. Our group has
successfully pursued a variety of model-independent approaches leading to
important results while being guided by the data rather than by models. We have
recently shown that SSS grating spectra that are dominated by emission lines on
top of continuum (SSe) experience more obscuration than those with pure
absorption line spectra (SSa). Compared to the large diversity of observed
phenomena, the current sample size is too limited for more conclusive trend
analyses. The extreme brightness in X-rays of novae during the SSS phase enables
expansion of the available sample of SSS at low cost.

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.
