Doppler effect?
Since this is not my area of expertise, I searched Google under the key words "star speed measure astronomy" to get these possible sources:

http://spiff.rit.edu/classes/phys240/lectures/expand/expand.html
http://en.wikipedia.org/wiki/Doppler_effect

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps a little more.
