Title: Rotation Periods of Quiescent Sun-like Stars

Abstract: We request time to use NRES in shared-risk mode at the 1-m LCO telescope in CTIO. Our program aims to monitor temporal changes in spectral lines that are chromospherically or sunspot sensitive. Our goal is to characterize the degree to which this technique can provide a measure of stellar rotation periods for older less-active Sun-like stars where photometric means fail. The result promises to open a new field of ground-based observations of older Sun-like stars whose ages provide an important window on the time evolution of planetary systems.
