| Abstract | Our CXO and XMM follow-ups of the outburst of V1647 Ori have shown stronglyenhanced variable X-ray emission, occuring as a consequence of the high diskaccretion rate. Our analysis of the combined X-ray datasets indicates thatX-rays emerge with a 0.7 day periodicity, which is consistent with a modulationby the Keplerian rotation of the inner accretion disk. New longer X-rayobservations are crucial to confirm this periodicity because, if correct, thisresult provides a unique view of the source of high energy emission and woulddramatically confirm that the X-ray outburst of V1647 Ori emerges from thestar-disk interaction region. Moreover, the new X-ray absorption measurementwill allow a temporal study of the mass-loss. We request a 120 ks XMM/EPIC. |

| 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. |
