RR Lyrae velocity
-
The variable star in AGZ000awk9 image cutout has, in comparison with other regular stars, a large cz= -289 +/- 5 km/s ( yay metric system!)
Is this caused by having a huge velocity or simply by its ( far away?) position in the Milky Way?
Ps yes relativity / all relative i know

High velocity stars. This cz velocity corresponds to a Redshift (z) -0.001, which may mean that it is moving towards us, or it may a error of measurement, and it is actually 0.000
We sometimes see stars in our galaxy with small redshifts. Look at the these links, but so far Galaxy Zoo hasn't found a real hypervelocity star to call our own.
white dwarf star, high velocity z 0.0028
