|Title||Pulsations and long term variability of the second eclipsing HMXB in M 33|
|Author||Dr Wolfgang Pietsch|
|Description||We propose 11 observations with about 3.4 day spacing of the second eclipsing high mass X-ray binary in M33. We will search for pulsations of the source down to 200ms and for an expected long term modulation of the source similar to the 35 day cycle of Her X-1. The results will allow us to decide whether the compact object in the system is a neutron star or a black hole. The Doppler delay curve of pulsations, if present, combined with the well determined orbital period could provide the mass function of the system.|

|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.
