|4U0114+65 outer wind
|Dr Jose Torrejon
|We propose to use the unique high resolution capabilities of XMM-Newton to study in depth the stellar wind structure and properties of the B supergiant donor in the wind accreting pulsar 4U0114+65. The goal is to put further observational constrains on the current models of stellar winds in massive stars using the point like source of ionizing X-rays as a probe. In particular we want to study the ionized wind of 4U0114+65 in the outer region r &amp;gt; 2R which, to date, remains largely unexplored (most ionized winds are studied at r &amp;lt; 2R , where the wind instabilities are already well developed) and answer a funda- mental question: is the wind clumped or smooth at r &amp;gt; 2R ?

|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.
