| Description | GT-The complex region centered on the massive star Eta Carinae is a natural target for the RGS: the object harbors a point-like X-ray source, as well as a resolved X-ray nebula, with an unusual and likely complex spectrum. CCD spectroscopy with ASCA has revealed (expected) large abundance anomalies, such as a strong N overabundance. The RGS has much higher effective spectral resolving power than any other astrophysical spectrometer for study of the extended nebula, and can address such issues as the line excitation mechanism(s) and non-equilibrium effects, and their distribution among the various spatial components. A proper understanding of these issues is a prerequisite for reliable abundance determinations. |

| 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. |
