How does the spectral line differ between two identical stars when one rotates faster than the other?
The spectral emission lines of a star that is rotating faster will be spread out from the central intensity more than the lines of a star that is rotating slower. This is because the limbs of the star are moving faster away from the viewer on one site and toward the viewer on the other, inducing a larger Doppler shift in the light originating from those regions of the star.
