Balmer Lines, Effective Temperatures

Scientific paper

Theoretical work on the self-broadening of Balmer lines by us predicts a large impact on model profiles, and therefore effective temperature determinations, particularly in metal-poor stars. We present initial results of the application to observations of a sample of cool dwarf stars. The effective temperatures determined for our sample show much improved agreement with the infra-red flux method results in the literature when compared with analysis using the previously available broadening theory.
