A pair of stars rotates about a common centre of mass. One of the stars has a mass M and the other has mass m such that =2m. The distance between the centres of the stars is d ( d being large compare to the size of eithe star). The period of rotation of the stars about their common centre of mass ( in terms of d,m,G) is

A pair of stars rotates about a common centre of mass. One of the stars has a mass M and the other m . Their centres are a distance d apart, d being large compared to the size of either star. Derive an expression for the period of revolution of the stars about their common centre of mass. Compare their angular momenta and kinetic energies.

In a binary star system one star has thrice the mass of other. The stars rotate about their common centre of mass then :

A binary star consists of two stars A(mass 2.2 M_s) and B (mass 11 M_s) where M_s is the mass of the sun, they are separted by distane d and are rotating about their center of mass, which is stationary. The ratio of the total angular momentum of the binary to the angular momentum of star B about the centre of mass is
