If a star is moving away from you the absorption lines in its spectrum will?

If a star is moving away from you, the emission lines in its spectrum will be shifted

toward longer wavelengths/lower frequency/the red end of the spectrum, since they

originate on the star itself.

But there's no effect on the absorption lines, because those are caused by material

that's unrelated to the star, and just happens to be in the line of sight between the

star and you.
