Tracers of Chromospheric Structure: Observations of CaII K and Hα in M Dwarfs
Abstract
We report on our 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 the results of our observing program so far, and discuss the application of these results as empirical constraints on models of quiescent M dwarf atmospheres. We also present initial model calculations and place them in the context of the data.
