Cool Stars 14 - Submitted Abstract # 34 This version created on 05 October 2006 Observations of Chromospheric Lines in Cool Dwarfs Lucianne Walkowicz, University of Washington Suzanne Hawley, University of Washington We have undertaken an observing program to capture simultaneous high resolution spectra of Ca II and Balmer lines in a sample of nearby M3 dwarfs. Our goal is to investigate the chromospheric heating required to produce both of these lines at the observed levels. We present here the initial results of our observing program, and discuss their future application as empirical constraints on static models of quiescent M dwarf atmospheres. ----------------------------------
