We attribute this to stellar rotation. Despite the great ages of halo stars, for G202-65, BD+51:1817 and Wolf 550 we infer vsini = 8.3 +/- 0.4, 7.6 +/- 0.3, and 5.5 +/- 0.6 km/s respectively. The stated errors are 3sigma. For CD-31:19466 we derive a 3sigma upper limit vsini < 2.2 km/s. The three rotating stars are known spectroscopic binaries. We explain the high rotation velocities in terms of mass and angular momentum tr","authors_text":"Scott G. Gregory, Sean G. Ryan, Timothy C.
