| Description | Epsilon Lupi is the only close binary star system where both massive main-sequence components have strong magnetic fields. Thus it is a natural laboratory for the study of the influence of magnetism on binarity. We have discovered radio emissions from this system that revealed double-peaked enhancement near the periastron phase, as well as pseudo-cyclic variations across the orbital phase. The double-peak enhancement is likely to be an effect of magnetospheric interaction. If this scenario is correct, one would also expect X-ray counterparts to the radio enhancements in the form of enhancement in the X-ray light curve at similar phases. Thus we request 55 ks of XMM-Newton time to search for the evidence of magnetospheric interaction and orbital variability in our unique target. |

| 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. |
