Scientific paper

Photoelectric lightcurves of the double-lined spectrum eclipsing binaries RS Cha, RZ Cha, and HS Hya, known as detached systems, have been studied by means of Wood's program in order to obtain homogeneous photometric elements. Masses, radii, and luminosities are given. HS Hya has not appreciably evolved from the ZAMS, whereas RS Cha and RZ Cha are close to the end of the main sequence evolutionary stage.
