The image below depicts a binary star system, with Star A and Star B shown in four different parts of their orbit around a common center of mass. Both stars orbit in circles, with Star B having a larger radius for its orbit. In all four images, the Earth is far below the stars, so that Star A is traveling directly toward the Earth at time 1. At times 1 and 3, what type of Doppler shift does each star's spectrum have, and which star will show a larger shift in its spectrum when viewed from Earth? The orbital mechanics might not be obvious here, but you can assume that Star B is traveling faster than Star A in its orbit. To see why, check out this animation \( \boldsymbol{G} \) and remember back to the "ant on a record player" idea. Shown below are 9 spectra. The stars have the same composition and, if not moving, would have the spectrum showed in A. At each time, select what spectrum the Earth would seen when looking at the binary stars from afar. The dashed line shows the unshifted absorption line.
