| Abstract: | We derive the blue fraction for a sample of K-selected galaxies in 25 clusters at 0.15 <z<0.92. We find a much smaller blue fraction and weaker trend with redshift than measured in optically selected samples. We suggest that the Butcher-Oemler effect is primarily due to star forming low luminosity galaxies. This revised version was published online in July 2006 with corrections to the Cover Date. |
