Question

An astronomer whose secret hobby is riding merry-go-rounds has dedicated his career to finding the stars that rotate the most rapidly. But the stars are all very far away, so none of them can be seen to spin even when he looks through the largest telescopes. How then can he identify the stars that rotate rapidly?

Answer 1

The correct answer would be, stars that rotate have much wider lines in their spectra than stars that do not.

But the stars are all very far away, so none of them can be seen to spin even when he looks through the largest telescopes. He can identify the stars that rotate rapidly through their spectra.

Explanation:

An astronomer who wants to find the stars that rotate most rapidly, needs to know the characteristics of stars he wants to find out.

So because stars are far away and astronomers can't look them even through the largest telescopes, they need to distinguish the rapidly moving stars with the ones that do not move rapidly, through their spectrum.

This is because the rapidly moving stars have much wider lines in their spectra than stars that do not move that rapidly.
