A binary star system consists of two stars revolving about their common center of mass. If we observe the light reaching us from one of these stars as it makes one complete revolution, what does the Doppler effect predict will happen to this light?

Answer #1

There will be two scenarios. 1 when the star will approaching towards us in that case the frequency of the light observe will be greater than the actual light emitted by the star blue shift will be observed. Another case when the star will move away from the observer the frequency observed will be less than the the actual frequency! Since it is moving in a circular path the red shift and the blue shift will be e study increasing and reaches maximum value when the tangential velocity of the star is parallel to the the line of observation. And when the tangential velocity of the star is perpendicular to the the line of observation there will be no Doppler shift

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).

The spectral lines of two stars in a particular eclipsing binary system shift back and forth with a period of 7 months. The lines of both stars shift by equal amounts, and the amount of the Doppler shift indicates that each star has an orbital speed of 1.1×105 m/s relative to the other. What are the masses of the two stars? Assume that each of the two stars traces a circular orbit around their center of mass. (Hint: See Mathematical...
