Scientific paper

We report new photometric observations and a new determination of the fundamental stellar parameters for the low-mass pre-main sequence eclipsing system RX J0529.4+0041A based on high-precision, near-IR (JHK) differential photometry obtained using adaptive optics at the ESO-La Silla 3.6 m telescope, and UBV(RI)C CCD photometry performed with the OIG camera at TNG. The new photometric data, in combination with already published photoelectric photometry and solution of the radial velocity curve, yield a more precise determination of the absolute dimensions and masses as well as of other basic physical properties of the components.
Based on observations carried out at ESO, La Silla, Chile, (ESO prop. 66.C-0469, 68.C-658) and at TNG, La Palma, Spain (TAC 4_06).
