|In-situ measurements of the heavy ion content of the elusive polar solar wind
|Dr Konrad Dennerl
|We propose to investigate the heavy ion content of the elusive polar solar wind by observing the cometary X-ray emission which results from charge exchange between solar wind heavy ions and cometary neutrals, thus providing in-situ information. We will utilize the favorable opportunity that during AO-16 we will approach solar minimum, where the polar wind will have expanded to lower latitudes, and that a bright comet, C-2015 V2, will be continuously observable for XMM from -2 deg to -32 deg ecliptic latitude. This observation is perfectly tailored to XMM, as it makes full use of its high soft X-ray sensitivity, its spectral, temporal, and spatial resolution, its full field of view, and of all six (PN, MOS1, MOS2, RGS1, RGS2, OM) of its scientific instruments.

|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.
