Plaskett's binary system consists of two stars that revolve in a circular orbit about a center of mass midway between them. This statement
implies that the masses of the two stars are equal (see figure below). Assume the orbital speed of each star is V| = 200 km/s and the
orbital period of each is 11.5 days. Find the mass M of each star. (For comparison, the mass of our Sun is 1.99 x 1030 kg.)

Plaskett's binary system consists of two stars that revolve in a circular orbit about a center of mass midway
between them. This statement implies that the masses of the two stars are equal (see figure below). Assume
the orbital speed of each star is v| = 225 km/s and the orbital period of each is 11.6 days. Find the mass M
of each star. (For comparison, the mass of our Sun is 1.99 x 1030 kg.)

Part 1 of 3 - Conceptualize
From the given data, it is difficult to estimate a reasonable answer to this problem without working through
the details and actually solving it. A reasonable guess might be that each star has a mass equal to or slightly
larger than our Sun because fourteen days is short compared to the periods of all the Sun's planets.
Part 2 of 3 - Categorize
The only force acting on each star is the central gravitational force of attraction which results in a centripetal
acceleration. When we solve Newton's second law, we can find the unknown mass in terms of the variables…
Two stars M, and M, of equal mass make up a binary star system. They move in a circular orbit that has its center at the midpoint of the line that separates them. If
M, - M, - 1.45 sm (solar mass), and the orbital period of each star is 1.70 days, find their orbital speed. (The mass of the sun is 1.99 x 10 kg.)
