One of the most effective ways to measure the speed of axial rotation of heavenly bodies, the study of the spectral lines is Phnshdgy. Here's how to record the spectrum of the star right arm (Alderamin) will be described. Then we spectral lines of the star Broadening factors influencing the spectral line, we can calculate the velocity of axial rotation.
