Abstract | Observations from XMM-Newton and other X-ray telescopes have shown howrelativistic disk lines, together with the thermal continuum, can be used toprecisely constrain the nature of the compact object in XRB systems, as well asthat of the accretion flow. The importance of XMM-Newton in the study of blackhole binaries cannot be overemphasised; with a single 40ksec (total) XMM-Newtonobservation of XTE J1752-223 (AO-9), we found that --- at least for thisspecific source --- state transition is not a manifestation of a change in theinner extent of the accretion disk; we confirmed the black hole nature of thecentral source; and constrained its dimensionless spin parameter. Here, wepropose to build on this success through a single 40ksec (total) ToO observation of a black hole transient in outburst. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
