Scientific paper

Wood's (1972) model is used in analyzing Przybylski's (1981) UBV light curves of the eclipsing binary HD 134518. Photometric solutions, coupled with what are considered plausible assumptions about its masses, suggest that, in contrast to earlier opinions, the binary is a detached main sequence system. It comprises a late A star and a considerably fainter and smaller K star. A table giving the photometric elements of HD 134518 is included. The binary is thought to be at a distance of 250 pc. The computations show that the primary minimum is an annular transit. The temperature difference between the two stars is approximately 3600 K.
