Possible intrinsic blueshift of Cepheid variable stars in the Milky Way?
Michael Gmirkin — (archived)

Was forwarded an interesting set of articles/papers recently:

(Pinning down the Milky Way's spin)

http://www.eso.org/public/outreach/press-rel/pr-2008/pr-30-08.html

(High-resolution spectroscopy for Cepheids distance determination)

http://www.aanda.org/10.1051/0004-6361:200809587/pdf

Though that HZ members might find them interesting.
