In a double-star system, two stars of mass 4.8 x 1030 kg each rotate about the system's center of mass at radius 1.4 x 1011 m. (a) What is their common angular speed? (b) If a meteoroid passes through the system's center of mass perpendicular to their orbital plane, what minimum speed must it have at the center of mass if it is to escape to “infinity” from the two-star system?

Two stars M_1 and M_2 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_1=M_2=5.45 sm (solar mass), and the orbital period of each star is 2.70 days, find their orbital speed. (The mass of the sun is 1.99x10^30kg).

Four stars, each having a mass M, are situated in a square pattern (each star is at the corner of the square) and are rotating about the system's center of mass. At what speed must they move for the system to maintain its square shape, such that the system does not collapse due to mutual gravitational attraction of the stars? Assume a side length of a for the square, and express your answer in terms of M, G, and a.
