| Description | GT-zeta Ori, a late O type supergiant, is a strong X-ray source. The X-rays originate from shocks in the stellar wind. The observations will be used to establish the physical conditions and elemental abundances in the shocked material. With models of line transfer in moving atmospheres we will determine the volume filling factor and depth distribution of the shocked gas pockets. This will help to constrain the still unknown mechanism that triggers these shocks. zeta Ori will be in the RGS focus. The surrounding field is a star formation region with many X-ray sources. We will use the EPIC cameras to study this complete field as well. The pn will be used in full window mode, one MOS with window2 and the other MOS in timing mode. All EPICs will use the thick filter. |

| 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. |
