Since the distance between the stars does not change by condition, each of the stars will move in a circle. The radii of the orbits of stars relative to the center of mass are inversely proportional to their masses. If the mass of one star is significantly greater than the mass of another, then in practice it will turn out that a low-mass star moves around a more massive one.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
