Scientific paper

The pre-main-sequence (PMS) eclipsing binary TY CrA exhibited a strange flux increase apparently coincident with primary eclipse in an XMM observation on March 2003. Because the flux increase occurred when the star was in an active state, it may have been produced by inter-binary magnetic activity, a mechanism that is new to stellar X-ray emission. To test this hypothesis, we propose observations of the low-mass PMS binary RX J0529.4+0041 during eclipse. These observations will put useful constraints on the location of the X-ray plasma even if no increase in X-ray emission is observed during the eclipse. We also propose a short observation of the young intermediate-mass eclipsing binary EK Cep to measure the X-ray activity level from this star for comparison.
