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 () differential photometry obtained
using adaptive optics at the ESO-La Silla 3.6 m telescope, and
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.
Key words: stars: pre-main sequence / stars: binaries: eclipsing / stars: binaries: spectroscopic / stars: fundamental parameters / stars: individual: RX J0529.4+0041 / stars: binaries: close
