Abstract

The University of Arizona Radial Velocity Spectrometer is probably capable of attaining a resolution of 100 m/s or less on slowly rotating stars of blue magnitude 5.5 or brighter and pulsation periods of 0.02 days or greater in the δ Scuti instability region of the H-R diagram. Such performance is approximately equivalent to a photometric resolution of 10−3 magnitudes, and thus represents a possible means of improving the detectability of δ Scuti pulsations by an order of magnitude. The instrument is briefly described and a high priority observing program is outlined.
