Problem 20DQ

Stars other than our sun normally appear featureless when viewed through telescopes. Yet astronomers can readily use the light from these stars to determine that they are rotating and even measure the speed of their surface. How do you think they can do this?

Step-by-Step Solution:
Step 1 of 3

Solution 20DQ By stellar rotation, we check the spectral lines observed from a star. These spectral lines give the exact information about the constituents of the star, the rotational speed and many things. The rate of rotation of a star creates some equatorial bulge due to the centrifugal force, as the star is made up of gases. The equator can rotate at a different speed than the higher latitude places. By the interaction of the magnetic field of the star with the stellar wind also we can predict the rate of rotation. These are all a part of astronomical spectroscopy which is beyond the scope of this course. Otherwise we would have discussed the various spectral lines by different types of rotation and vibration
