Cool Stars 14 - Submitted Abstract # 267 This version created on 05 October 2006 A 1 sq. Degree BVI Survey of IC 4665: New Insights into Rotation, Magnetic Activity and Lithium Evolution During the Late Pre-main Sequence. David James, Vanderbilt University Phillip Cargile, Vanderbilt University Willem-Jan de Wit, Observatoire de Grenoble Christopher Saling, Vanderbilt University We present high quality results of a 1 sq. degree CCD BVI survey of the central region of the young (30-50 Myr) cluster IC 4665. These data are compared to less robust, and in some cases 'relative', photometry results presented by Prosser (1993), whose survey only covered the central 41' x 32' square region. Our dataset will be used to derive more accurate physical stellar parameters for the cluster's solar-type members, in order to re-assess the available rotation period, X-ray luminosity and lithium abundance data ensembles which already exist for this cluster. Evolution comparisons will be made to the similar-age clusters NGC 2547, IC 2391 and IC 2602, as well as to early pre-main sequence stars in the Orion Nebula Cluster (~1 Myr) and main sequence stars in the Pleiades (80-100 Myr). ----------------------------------
