Scientific paper

Classical R-M and synthetic W-D analysis of V758 Centauri are presented. Two solutions (semi-detached and contact) were found from differential corrections approach. The semi-detached model is physically acceptable since the system is thermally decoupled. The solution for this case and the photometric data are consistent with a B9 primary and A9 secondary components having parameters close to main-sequence values. It is suggested that V758 Centauri is a B-type W UMa system at the broken-contact phase predicted by the Thermal Relaxation Oscilllations theory.
