To find the masses of both stars in a binary system, you must find the velocity of each star, the period of the orbit, and the average distance between the stars.
The displacement covered by an object in the unit of time is called velocity.
The formula of velocity is v = d/t and its dimensions are LT-1.
A unit of time in which a particle or object passes through a point to complete its one cycle is called a period. It is related to time.
The time-period is denoted by T and the formula is T = 2 π√ l / g.
In physics, distance is a vector quantity without any direction. It can be calculated as distance = speed x time i.e. d = v.t
