A Search for Southern Extreme-Velocity Stars Carney, Bruce W. ; Peterson, Ruth C. Abstract We are conducting a search for extreme-velocity stars as a means of placing a lower limit to the local value of the Galaxy's escape velocity. We report here the results of a survey of (largely) southern hemisphere proper-motion stars: 27 metal-poor F and G stars near the South Galactic Pole; 18 stars identified by Eggen as extreme-velocity candidates; and five other field stars. We obtained radial velocities and JHK photometry for almost all the stars, and some uvby and UBV photometry. Accurate distance moduli based on B - V, b - y, V - K, and J - K color indices are presented in conjunction with reddening and metallicity estimates. Kinematical properties of the stars are reported, including U, V, and W velocities, and the velocity in the Galaxy's rest frame, VRF. Five of the program stars were found to have VRF >380 km s-1.
