Birth and Evolution of Binary Stars, Poster Proceedings of IAU Symposium No. 200 on The Formation of Binary Stars, held 10-15 April, 2000, in Potsdam, Germany. Edited by Bo Reipurth and Hans Zinnecker, 2000, p. 9.
We announce the discovery of a low--mass pre--main sequence eclipsing binary among a sample of double-lined spectroscopic binaries found in the Orion star forming region in a previous high-resolution spectroscopic investigation on ROSAT--discovered weak-T Tauri stars (Alcalá et al. 2000). As our observing programme is presently going-on, we report here some preliminary results based on data collected till January 2000.
