The influence of the gravity darkening effect in the formation of a non iso‐thermal photosphere on close binary stars is presented. Furthermore, a theoretical model that describes thermal differences on the stars’ surfaces, based on the temperature gradient equations, has been constructed. Application on TY Pup has been made and presented.
