Abstract	In HD 209295, we have recently discovered both intermediate-order gravity mode and low-order pressure mode pulsations. It is therefore both a gamma-Doradus and a delta$-Scuti star, which makes it the first confirmed member of two classes of pulsating star. Our analyses reveal that the star is an SB1 binary, with an orbital period of 3.1 days, an eccentricity of 0.35 and a mass function of 0.042 solar masses. All observational evidence points to the secondary star being either a massive white dwarf or a neutron star. We propose to use theXMM-Newton observatory to discover and investigate the nature of HD 209295ssecondary using X-rays. This will allow us to refine the asteroseismologicalanalysis of the star through the greatly improved boundary conditions.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
