Description | Understanding the physics of the accretion flows around and onto compact object is a key goal of X-ray astrophysics. We propose to use XMM-Newton to obtain detailed X-ray spectra during the onset of an outburst of the soft X-ray transient Aql X-1. Exploiting regular and frequent optical monitoring of Aql X-1 already being carried out by members of our group, it will be possible to observe the onset of an outburst with XMM-Newton. This will provide direct tests of the disk instability model commonly used to describe the behavior of soft X-ray transients and will give new insights into the physics of the accretion flow. |

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. |
