Abstract The pre-main-sequence (PMS) eclipsing binary TY CrA exhibited a strange fluxincrease apparently coincident with primary eclipse in an XMM observation onMarch 2003. Because the flux increase occurred when the star was in an activestate, it may have been produced by inter-binary magnetic activity, a mechanismthat is new to stellar X-ray emission. To test this hypothesis, we proposeobservations of the low-mass PMS binary RX J0529.4+0041 during eclipse. Theseobservations will put useful constraints on the location of the X-ray plasmaeven if no increase in X-ray emission is observed during the eclipse. We alsopropose a short observation of the young intermediate-mass eclipsing binary EKCep to measure the X-ray activity level from this star for comparison.

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.
