Abstract
The theoretical model for the evolved close binary system LB 3459 recently proposed by Paczynski & Dearborn has several major flaws; it does not reproduce the well-defined shape of the primary eclipse nor the observed colour changes at primary and secondary eclipses and it assumes a mass ratio of unity which is very unlikely. The model predicts a velocity curve amplitude several times greater than that observed.Keywords
